HALOCYCLIZATIONS: THE CYCLIZATION OF HETEROCYCLIC OLEFINIC AMIDES AND UREAS
Balko, T. W.,Brinkmeyer, R. S.,Terando, N. H.
, p. 2045 - 2048 (2007/10/02)
The halocyclization of N-heterocyclicpentenamides and allylureas with N-bromosuccinimide yields the pyrrolidinones 3 and imidazolidinones 5, respectively.The thiazolylpentenamide also yields the 6-membered ring lactam.
