Abstract
α‐Azido‐γ‐lactone (2a–c) eliminieren in Äthanol mit katalytischen Mengen Natriumäthylat Stickstoff und lagern sich in die 2‐Amino‐buten‐(2)‐olide‐(4.1)5a–cum. Entsprechend entsteht aus 3‐Azido‐1‐methyl‐pyrrolidon‐(2) (7d) das 3‐Amino‐1‐methyl‐Δ3‐pyrrolon‐(2) (8d). Das α‐Benzylidenamino‐γ‐lacton11alagert unter diesen Bedingungen in das 2‐Benzyl‐amino‐buten‐(2)‐olid‐(4.1)14um.Keywords
