4-Alkoxythiocarbonylthio-and 4- (N, N-disubstituted thiocarbamoylthio) pyrazoles and two thiocyanatopyrazoles were synthesized. Antifungal activities of these compounds as well as those described in the preceding paper were tested. In conclusion, 4-thiocyanatopyrazoles showed high antifungal activities of which 1-(m-nitrophenyl)-4-thiocyanato-3, 5-dimethylpyrazole was most effective.
Treatment of α-(dimethylthiocarbamoylthio) ketones with bakers’ yeast afforded the corresponding chiral alcohols in high yields with high enantiomeric excess (in most cases, more than 96% ee). α-(Dimethylthiocarbamoylthio) aldehydes were reduced to give chiral α-(dimethylthiocarbamoylthio) alcohols in 69–92% yields with 32–63% ee, which were converted to chiral 1,2-epithio derivatives.
