Optically Active Antifungal Azoles. VI. Synthesis and Antifungal Activity of N-((1R,2R)-2-(2,4-Difluorophenyl)-2-hydroxy-1-methyl-3-(1H-1,2,4-triazol-1-yl)propyl)-N'-(4-substituted phenyl)-3(2H,4H)-1,2,4-triazolones and 5(1H,4H)-tetrazolones.
A new series of optically active antifungal azoles, N-[(1R, 2R)-2-(2, 4-difluorophenyl)-2-hydroxy-1-methyl-3-(1H-1, 2, 4-triazol-1-yl)propyl]-N'-(4-substituted phenyl)-3(2H, 4H)-1, 2, 4-triazolones (1, 2) and 5(1H, 4H)-tetrazolones (3), were prepared from the triflate derivative of (1S)-1-[(2R)-2-(2, 4-difluorophenyl)-2-oxiranyl]ethanol (13) by an SN2 displacement reaction with the anion of an azolone (17-19) and subsequent ring-opening reaction with 1H-1, 2, 4-triazole. The optically active oxiranylethanol 13 was synthesized from methyl (R)-lactate in a stereo-controlled manner. The azolones 1-3 prepared showed potent antifungal activities in vitro and in vivo.
The present invention relates to a hydrazine derivative represented by the formula (I): ##STR1## (wherein each of Ar.sup.1 and Ar.sup.2 is a substituted or unsubstituted phenyl group, a substituted or unsubstituted heteroaryl group, or the like, R.sup.1 is an alkyl group or the like, and A is a divalent radical having --C.dbd.N--N-- or --CH--NH--N-- as a fundamental skeleton), which is a useful compound as an agricultural and horticultural insecticide.
Photopharmacology uses molecular photoswitches to establish control over the action of bioactive molecules. The application of photopharmacology in the research of invertebrate sodium channels has not been investigated. Here we report several photochromic ligands of metaflumizone. One ligand, termed ABM04, underwent reversible trans–cis isomerization under ultraviolet or blue light irradiation. cis-ABM04
