Enamino acids derived from 1,2-dimethylaminomethylene- or 1,2-hydroxymethylene-carbonyl compounds and amino acids undergo a decarboxylative cyclisation to pyrroles, isoindoles and other fused pyrroles. A two atom ring expansion occurs preferentially with enamino acids from cyclohexane-1,3-diones and α-alkyl-α-amino acids leading to oxocino[2,3-c]pyrroles.
从 1,2-二甲氨基亚甲基或 1,2-羟基亚甲基羰基化合物和氨基酸中提取的烯氨酸经过脱羧环化反应生成吡咯、异吲哚和其他融合吡咯。环己烷-1,3-二酮中的烯氨基酸和 α-烷基-α-氨基酸会优先发生双原子扩环,生成氧代氨基[2,3-c]吡咯。
