Regioselective lithiation and functionalization of 3-(benzyloxy)isothiazole: Application to the synthesis of thioibotenic acid

Direct functionalization of the 3-oxygenated isothiazole heteroaromatic parental system has not yet been reported in the literature. Here, we report the first regioselective lithiation of the 5-position of 3-(benzyloxy)isothiazole (4) using LDA in diethyl ether. The versatility of the methodology was explored by quenching with a variety of electrophiles to give the desired products 7a,b,d-g in 54-68% yield. Only benzoylation aiming at the synthesis of 7c was unsuccessful. Furthermore, a highly convergent synthesis of thioibotenic acid (1), the sulfur analogue of the neurotoxic natural product ibotenic acid, was carried out.

Competitive antagonism of insect GABA receptors by 4-substituted 5-(4-piperidyl)-3-isothiazolols

gamma-Aminobutyric acid (GABA) receptors are important targets of parasiticides/insecticides. Several 4-substituted analogs of the partial GABA(A) receptor agonist 5-(4-piperidyl)-3-isothiazolol (Thio-4-PIOL) were synthesized and examined for their antagonism of insect GABA receptors expressed in Drosophila S2 cells or Xenopus oocytes. Thio-4-PIOL showed weak antagonism of three insect GABA receptors. The antagonistic activity of Thio-4-PIOL was enhanced by introducing bicyclic aromatic substituents into the 4-position of the isothiazole ring. The 2-naphthyl and the 3-biphenylyl analogs displayed antagonist potencies with half maximal inhibitory concentrations in the low micromolar range. The 2-naphthyl analog induced a parallel rightward shift of the GABA concentration-response curve, suggesting competitive antagonism by these analogs. Both compounds exhibited weak insecticidal activities against houseflies. Thus, the orthosteric site of insect GABA receptors might be a potential target site of insecticides. (C) 2014 Elsevier Ltd.

The antifungal activity of 4-amino-3-methyl-1 -phenylpyrazolo-(3,4-c)isothiazole was studied on Trichophyton rubrum. The compound, at concentrations between 20 and 100 mu g ml(-1), induces a remarkable reduction in the growth and causes deep morphogenetic anomalies. The ultrastructural modifications have demonstrated that the compound targets the cell membrane of the fungus, breaking down not only the endomembrane system, but also the ‘outer’ membrane, with consequent extrusion of materials in the medium. The results suggests a mechanism of action similar to other azoles clinically utilized.

Fused 1,2-dithioles – Part VII – Synthesis and reactions of 4H-1,2-dithiolo[4,3-c]isothiazoles

The 1,2-dithiolosultam derivative 14 was obtained from the (alpha-bromoalkylidene)propenesultam derivative 9 (Scheme 1). Regioselective cleavage of the two ester groups ( -> 1b or 2b) allowed the preparation of derivatives with different substituents at C(3) in the dithiole ring (see 27 and 28) as well as at C(6) in the isothiazole ring (see 17 – 21; Scheme 2). Curtitis rearrangement of the 6-carbonyl azide 21 in Ac2O afforded the 6-acetamide 22, and saponification and decarboxylation of the latter yielded ‘sulfothiolutin’ (30). Hydride reductions of two of the bicyclic sultams resulted in ring opening of the sultam ring and loss of the sulfonyl group. Thus the reduction of the dithiolosultam derivative 14 yielded the alkylidenethiotetronic acid derivative 33 (tetronic acid = furan-2,4(3H,4H)-dione), and the lactam-sultam derivative 10 gave the alkylidenctetramic acid derivative 35 (tetramic acid= 1,5-dihvdro-4-hydroxy-2H-pyrrol-2-one) (Scheme 3). Some of the new compounds (14, 22, 26, and 30) exhibited antimycobacterial activity. The oxidative addition of 1 equiv. of [pt(eta(2)-C2H4)L-2] (36a, L – PPh3; 36b, L = 1/2 dppf; 36c, L = 1/2 (R,R)-diop) into the S-S bond of 14 led to the cis(dithiolato)platinum(II) complexes 37a-c. (dppf=1,1′-bis(diphenylphosphino)ferrocene; (R,R)-diop([(4R,5R)-2,2-demithyl-1,3-dioxolane-4,5-diyl]bis(iiiethylene)bis(diphenylphosphine]).
