A one-pot procedure for the highly diastereoselective synthesis of 1-carbamoyl-4-amino-1,2,4,5-tetrahydroindolo[2,3-c]azepin-3-one derivatives is described. Using 2-formyl-L-tryptophan as a bifunctional building block, a catalyst-free Ugi-three-component reaction (Ugi-3CR) was developed to present trisubstituted indoloazepinones in good yields and excellent diastereomeric excess.
描述了一种用于高非对映选择性合成1-氨基甲酰基-4-氨基-1,2,4,5-四氢吲哚并[2,3 - c ]氮杂-3-酮衍生物的一锅法程序。使用2-甲酰基-L-色氨酸作为双功能结构单元,开发了无催化剂的Ugi-三组分反应(Ugi-3CR),以高收率和优异的非对映异构体过量提供了三取代的吲哚并ze庚酮。
