Amidoalkylation of 1,3-dienes with the adduct of glyoxylic acid-methyl carbamate (1) afforded α-acylamino-γ-alkenyl-γ-butyrolactones (e.g. 2, 6-9) in 40–80% yield and the pipecolic acid derivatives (e.g. 3) in less than 20% yield. An explanation is suggested to account for above results.
1,3-二烯与乙醛酸-氨基甲酸甲酯(1)的加成物进行酰胺烷基化,可得到40-80%产率的α-酰基氨基-γ-烯基-γ-丁内酯(例如2、6-9)和胡椒酸衍生物(例如3)的收率低于20%。建议解释以解释上述结果。
