Microwave-assisted novel and efficient one-pot synthesis of fused steroidal and non-steroidal isothiazoles

efficient microwave promoted one-pot synthesis of steroidal and non-steroidal isothiazole derivatives from corresponding beta-bromo-alpha,beta-unsaturated aldehydes has been described using a sodium thiocyanateurea system. The beta-bromo-alpha,beta-unsaturated aldehydes derivatives are efficiently synthesized from corresponding cyclic ketones using Vilsmeir formylation reaction. The synthetic protocol is also applied for the synthesis of antifungal brassilexin. (c) 2012 Elsevier Ltd. All rights reserved.

Skeletal Rearrangement of Twisted Thia-Norhexaphyrin: Multiply Annulated Polypyrrolic Aromatic Macrocycles

A hybrid thia-norhexaphyrin comprising a directly linked N-confused pyrrole and thiophene unit (1) revealed unique macrocycle transformations to afford multiply inner-annulated aromatic macrocycles. Oxidation with 2,3-dichloro-5,6-dicyano-1,4-benzoquinone triggered a cleavage of the C-S bond of the thiophene unit, accompanied with skeletal rearrangement to afford unique pi-conjugated products: a thiopyrrolo-pentaphyrin embedded with a pyrrolo[1,2]isothiazole (2), a sulfur-free pentaphyrin incorporating an indolizine moiety (3), and a thiopyranyltriphyrinoid containing a 2H-thiopyran unit (4). Furthermore, 2 underwent desulfurization reactions to afford a fused pentaphyrin containing a pyrrolizine moiety (5) under mild conditions. Using expanded porphyrin scaffolds, oxidative thiophene cleavage and desulfurization of the hitherto unknown N-confused core-modified macrocycles would be a practical approach for developing unique polypyrrolic aromatic macrocycles.

1-aryl-5-methoxypyrrolones as synthons for fused heterocycles

3-Di(methylsulfonyl)methylene-pyrrol-2-one and 2-(1-aryl-5-methoxy-2-oxo-2,3-dihydro-1H-3-pyrrolylidene)malononitrile were obtained from 1-aryl-5-methoxypyrrolones. Aziridine and hydroxylamine reacted with pyrrol-2-one to afford 2,7-diazaspiro[4.4]-nona-3,6-diene and oxime derivatives, respectively. Pyrrolo[2,3-c]isoxazoles or pyrrolo[2,3-c]isothiazole were formed in high yield from oximes depending upon the reaction conditions employed for ring closure. Treatment of pyrrolylidene malononitrile with N-1,N-2-di(4-chlorophenyl)acetamidine in ethyl acetate furnished azepine derivatives in 70-75% yield. (C) 2002 Elsevier Science Ltd.

Rational Design of Low-Band Gap Star-Shaped Molecules With 2,4,6-Triphenyl-1,3,5-triazine as Core and Diketopyrrolopyrrole Derivatives as Arms for Organic Solar Cells Applications

A series of D-A novel star-shaped molecules with 2,4,6-triphenyl-1,3,5-triazine (TPTA) as core, diketopyrrolo[3,4-c] pyrrole (DPP) derivatives as arms, and triphenylamine (TPA) derivatives as end groups have been systematically investigated for organic solar cells (OSCs) applications. The electronic, optical, and charge transport properties were studied using density functional theory (DFT) and time-dependent DFT (TD-DFT) approaches. The parameters such as energetic driving force Delta EL-L, adiabatic ionization potential AIP, and adiabatic electron affinity AEA were also calculated at the same level. The calculated results show that the introduction of different groups to the side of DPP backbones in the star-shaped molecules can tune the frontier molecular orbitals (FMOs) energy of the designed molecules. The designed molecules can provide match well with those of typical acceptors PCBM ([6,6]-phenyl-C61-butyric acid methyl ester) and PC71BM ([6,6]-phenyl-C71-butyric acid methyl ester). Additionally, the absorption wavelengths of the designed molecules show bathochromic shifts compared with that of the original molecule, respectively. The introduction of different groups can extend the absorption spectrum toward longer wavelengths, which is beneficial to harvest more sunlight. The calculated reorganization energies suggest that the designed molecules are expected to be the promising candidates for ambipolar charge transportmaterials except molecule with benzo[c]isothiazole group can be used as hole and electron transport material. Moreover, the different substituent groups do not significantly affect the stability of the designed molecules.

Antirhinovirus activity of 3-methylthio-5-aryl-4-isothiazolecarbonitrile derivatives

A series of 3-methylthio-5-aryl-4-isothiazolecarbonitriles has been evaluated as anti rhinovirus agents against a panel. of 17 representative human rhinovirus (HRV) serotypes, belonging to both A and B groups. No anti rhinovirus activity was detected for 3-methylthio-5-phenyl-4-isothiazolecarbonitrile (IS-2). Isothiazole derivatives with bulky substituents (O-Bn or O-But groups) on the para position of the phenyl ring were the most effective compounds of this series. In fact, a reduction in virus-induced cytopathogenicity was demonstrated for the O-Bn substituted IS-50 compound against the majority (88%) of the rhinoviruses tested, whereas the compound with an O-Ts group (IS-44) was found to be a specific inhibitor of group B serotypes, exhibiting the lowest IC50 against HRVs type 2, 85 and 89. Our studies on the mechanism of action of IS-44 demonstrated that it prevents the thermal inactivation of HRV 2 infectivity, probably due to a conformational shift in the viral capsid and a decrease in affinity for the cellular receptor, resulting in an inhibition of attachment of the virions.

In vitro and in vivo anticryptococcal activities of a new pyrazolo-isothiazole derivative

We investigated the activity of a pyrazolo-isothiazole derivative (G8) against Cryptococcus neoformans. A first screening test showed that G8 at 10 mg/L inhibited the growth of 14 of 15 clinical isolates tested. Killing experiments showed that fungicidal activity was achieved after 8 h of treatment with G8 at concentrations greater than or equal to10 mg/L. In a murine model of systemic cryptococcosis, G8 was effective at prolonging survival compared with the controls. Our data indicate that this new derivative has a potential therapeutic role in infections caused by C. neoformans.
