Cyclofunctionalization of Olefinic Urethanes and Ureas with Halogens. Synthesis of 1-Substituted Spiro-2'(1'H)-one Derivatives

The cyclization reaction of 4-(2-carbamoylaminophenyl)-1,2,5,6-tetrahydropyridine derivatives (9) and a 4-(2-methoxycarbonylaminophenyl)-1,2,5,6-tetrahydropyridine derivative (4) with halogen was investigated.Treatment of the former (9) with bromine or N-
