the stereochemistry of HPA-12, an important ceramide-trafficking inhibitor that was discovered and synthesized and its stereochemistry determined in 2001, the synthesis and the stereochemistry were reinvestigated. A large-scale synthetic method for HPA-12 based on a Zn-catalyzed asymmetric Mannich-type reaction in water was developed. Single crystals of HPA-12 for X-ray crystallographic analysis were
响应伯克什(Berkeš)的报告,修改和合成了重要的神经酰胺贩运抑制剂HPA-12的立体化学,并于2001年确定了其立体化学,对此合成和立体化学进行了重新研究。提出了一种基于锌催化水中不对称曼尼希型反应的HPA-12大规模合成方法。由丙酸乙酯/获得用于X射线晶体学分析HPA-12的单晶Ñ己烷,和立体化学明确确定为1 - [R,3小号,与贝尔克斯订正结构一致。
