Abstract The title compounds (7c,d) have been prepared by the Z to E isomerization (NaNC2, HNO3) of the corresponding Z-lactones (6c,d), which are stereoselectively available (H2, Lindlar cat.) from the acetylenic lactones 4a-d, prepared earlier from cycloalkanones.
摘要 标题化合物 (7c, d) 是通过相应的 Z-内酯 (6c, d) 的 Z 到 E 异构化 (NaNC2, HNO3) 制备的,这些 Z-内酯可立体选择性地从炔内酯中获得 (H2, Lindlar cat.) 4a-d,较早由环烷酮制备。
