An optimized process for the stereospecific synthesis of carbacephem key intermediates 3β-[4-(S)-phenoxyacetylamino-4β-[2-(2-furyl)ethyl]azetidin-2-one (1) and 3β-[4-(S)-phenyl-acetylamino-4β-[2(2-furyl)ethyl)]azetidin-2-one] (2) is described. This report provides an efficient and cost-effective process for achieving a consistent yield and quality of intermediates 1 and 2 via Birch reduction employing
碳头孢烯关键中间体 3β-[4-(S)-phenoxyacetylamino-4β-[2-(2-furyl)ethyl]azetidin-2-one (1) 和 3β-[4-(S) 立体定向合成的优化工艺)-苯基-乙酰氨基-4β-[2(2-furyl)ethyl)]azetidin-2-one] (2) 进行了描述。本报告提供了一种有效且具有成本效益的工艺,通过使用钠/氨代替锂/氨系统的 Birch 还原来实现中间体 1 和 2 的一致产率和质量。
