Lewis acid mediated diastereoselective keto-ene cyclization on chiral perhydro-1,3-benzoxazines: synthesis of enantiopure cis-3,4-disubstituted 3-hydroxypyrrolidines

Andrés, Celia,González, Israel,Nieto, Javier,Rosón, Carlos D.

experimental part, p. 9728 - 9736 (2010/02/27)

Chiral 2-acyl-3-allyl-perhydro-1,3-benzoxazines derived from (-)-8-aminomenthol were easily cyclized in the presence of Lewis acids at 0 °C. The diastereoselectivity of the cyclization was dependent on the nature of the Lewis acid. The cyclization compoun
