The methanesulfonates of (α-(4-chlorophenyl)-α-[1-(2-chlorophenyl)ethenyl]-1H-1,2,4-triazole-1-ethanol and α-[1-(2-chlorophenyl)ethenyl]-α-(2,4-difluorophenyl)-1H-1,2,4-triazole-1-ethanol (1a, b) are orally effective α-styryl carbinol derivatives developed for the treatment and prevention of systemic fungal infections. Practical new processes amenable for the large-scale production of these compounds
(α-(4-氯苯基)-α-[1-(2-氯苯基)乙烯基] -1 H -1,2,4-三唑-1-乙醇和α-[1-(2-氯苯基)的甲磺酸盐乙烯基]-α-(2,4-二氟苯基)-1 H -1,2,4-三唑-1-乙醇(1a,b)是开发用于治疗和预防系统性真菌感染的口服有效α-苯乙烯基甲醇衍生物。描述了适合大规模生产这些化合物的实用新方法,值得注意的是选择二氯苯乙烯作为苯乙烯基部分的便利前体,将敏感的格氏试剂改性为现实的制备反应,以及使用1, 2,4-三唑同时作为碱基转移剂和亲核试剂。
