An easily handled one-pot synthetic procedure was previously developed for the synthesis of bisphosphinates starting from acyl chlorides. Herein, other trivalent derivatives as acid anhydrides and activated esters were tested to form various bisphosphinates. This modulation of the reactivity can be controlled according to the nature of the acid derivative for the use of sensitive and functionalized substrates.

The first oxidative coupling of alkylnitriles with aromatic carboxylic acids using di-tert-butyl peroxide (DTBP) as oxidant was achieved under the catalysis of ionic Fe(III) complexes bearing an imidazolinium cation. This protocol features nontoxic iron catalysis, direct alpha-C(sp(3))-H bond oxidative esterification of alkylnitriles, non-prefunctionalized starting materials, and a broad substrate scope with outstanding steric hindrance tolerance, providing a novel, straightforward, and green approach toward cyanomethyl ester synthesis.

Enantioselective electrophilic three-component thioarylation of alkenes by chiral selenide catalysis with free phenols as arylating sources is disclosed. A variety of chiral phenols were achieved in high regio-, enantio-, and diastereoselectivities. Mechanistic studies revealed that this transformation went through carbon nucleophilic attack to give the products rather than the process of intramolecular rearrangement of phenolic ether intermediates. The application of this organocatalytic method in the alkylation of methoxy-substituted benzenes elucidated its generality.

Diene-transmissive Diels-Alder (DTDA) sequences are extraordinarily powerful processes for the generation of fused bicyclic systems. Nonetheless, only stable dienophiles have previously been deployed. Herein we report DTDA sequences with a variety of substituted [3]dendralenes in the first study to deploy arynes as dienophiles. We demonstrate the one-flask generation of complex, aromatic-ring-containing, multicyclic systems of relevance to medicinal chemistry. These synthetic operations provide numerous successful examples of the otherwise challenging and rarely reported intermolecular Diels-Alder reaction of acyclic 1,3-butadienes with arynes, which is made possible due to the exalted reactivity of dendralenic dienes.

An article Pd(II)-Catalyzed Enantioselective gamma-C(sp(3))-H Functionalizations of Free Cyclopropylmethylamines WOS:000551495700013 published article about C-H ACTIVATION; ORTHO-ARYLATION; AMINO-ACIDS; BONDS; DIVERSIFICATION; CARBONYLATION; BIDENTATE; ROUTE in [Zhuang, Zhe; Yu, Jin-Quan] Scripps Res Inst, Dept Chem, La Jolla, CA 92037 USA in 2020, Cited 38.

Prized for their ability to reliably forge stereocenters with precise regiocontrol from simple and abundant starting materials, substrate-directable enantioselective reactions are widely used in modern organic synthesis. As such, enantioselective C(sp(3))-H functionalization reactions directed by innate functional groups could provide new routes to introduce molecular complexity within the inert hydrocarbon moiety, but to date this approach has been met with little success. While free primary aliphatic amines are common, versatile intermediates in synthesis, they are traditionally unreactive in C(sp(3))-H activation reactions. Herein we report the Pd-catalyzed enantioselective C(sp(3))-H functionalization of free aliphatic amines (cyclopropylmethylamines) enabled by a chiral bidentate thioether ligand. This ligand’s privileged bidentate coordination mode and thioether motif favor the generation of the requisite mono(amine)-Pd(II) intermediate, thus enabling the enantioselective C-H activation of free amines. The resulting C-Pd(II) species could engage in either Pd(II)/Pd(IV) or Pd(II)/Pd(0) catalytic cycles, enabling access to a diverse range of products through (hetero)arylation, carbonylation, and olefination reactions. Consequently, this versatile reactivity offers medicinal chemists a general strategy to rapidly prepare and functionalize biologically relevant amines.

Using gem-difluoromethylene alkynes as effectors, unprecedented diverse C-H activation/[4+2] annulations of simple benzoic acids are reported. The chemodivergent reaction outcomes are well-tuned by Rh/Ir-catalyzed system; in the Rh-III catalysis, 3-alkenyl-1H-isochromen-1-one and 3,4-dialkylideneisochroman-1-one skeletons are afforded in a solvent-dependent manner whereas difluoromethylene-substituted 1H-isochromen-1-ones are generated under the Ir-III-catalyzed system. Mechanistic studies revealed that unusually double beta-F eliminations and fluorine effect-induced regioselective reductive elimination are independently involved to enable distinct reaction modes for divergent product formations. Besides, synthetic application in both the derivatization of obtained diene products and the on-DNA synthesis of DNA-tagged difluorinated isocoumarin have been demonstrated, which manifested great potential for synthetic utility of the developed protocols.

Herein, we describe two novel strategies for the synthesis of esters, as achieved under high-speed ball-milling (HSBM) conditions at room temperature. In the presence of I-2 and KH2PO2, the reactions afford the desired esterification derivatives in 45% to 91% yields within 20 min of grinding. Meanwhile, using KI and P(OEt)(3), esterification products can be obtained in 24% to 85% yields after 60 min of grinding. In addition, the I-2/KH2PO2 protocol was successfully extended to the late-stage diversification of natural products showing the robustness of this useful approach. Further application of this method in the synthesis of inositol nicotinate was also discussed.

Solid-state acid-responsive materials are promising for the tunability of their intrinsic properties. However, the relationship between molecular structure and emission shift as a response to acid stimuli has not been systematically studied. Herein, we report the effect of protonation and subsequent intramolecular hydrogen bonding on the photophysical properties of compounds (MPP-s, MPP-d, and MPP-d-CN) with different conjugation modes between the electron-donating dimethoxyl phenyl and the electron-withdrawing benzothiazole ring. The results established that the stronger the intramolecular charge transfer feature of the compound, the smaller is the emission shift after acid stimuli. Our studies also indicated that the conjugation mode significantly affected the solid-state packing mode: MPP-s and MPP-d tended to form dimers, while MPP-d-CN exhibited the strongest aggregation-induced emission enhancement (AIEE). The exploration of structure-property relationship would provide experimental and theoretical guidance in designing acid-responsive molecular switches and developing high-performance AIEE-active luminogens.
