An asymmetric synthesis of the spermidine alkaloid (+)-cyclocelabenzine (1a) and its (−)-(13S)-epimer 1b is described using optically active (+)-(3S)-3-amino-3-phenylpropionic acid as the chiral building block. The isoquinolin-1-one fragment 15 was synthesized by a modified Bischler-Napieralski reaction. The relative configuration of the (−)-isomer was determined by an X-ray crystal-structure analysis
的亚精胺生物碱(+)的不对称合成- cyclocelabenzine(1A)和它的( - ) - (13小号)差向异构体1B是使用光学活性的(+)中所述- (3-小号)-3-氨基-3-苯基丙酸作为手性构件。异喹啉-1-酮片段15通过改良的Bischler-Napieralski反应合成。(-)-异构体的相对构型是通过X射线晶体结构分析确定的,这使我们能够确定天然(+)- 1a的绝对构型为(8 S,13 R)。
