Butenolides or α,β-unsaturated lactams 1 react with 1,2-diamines cysteamine or 2-aminothiophenol by addition and ring transformation giving new chiral, hydrogenated or partly hydrogenated 7-(α-hydroxyalkyl) and 7-(α-aminoalkyl)-1,4-diazepin-5-ones and 1,4-thiazepin-5-ones 4.
丁烯内酯或α,β-不饱和内酰胺1通过加成和环化反应与1,2-二胺半胱胺或2-氨基硫酚反应,得到新的手性,氢化或部分氢化的7-(α-羟烷基)和7-(α-氨基烷基)- 1,4-二氮杂-5-酮和1,4-噻氮-5-酮4。
