Highly Stereoselective Syntheses Involving N-Alkyl-4,4,7α-trimethyl-trans-octahydro-1,3-benzoxazine Intermediates. 2

Previously studied highly stereoselective additions of Grignard, organolithium, and hydride reagents to the 2-benzoyl derivative of compound 1a have been extended to other 2-alkanoyl derivatives (1, R'= methyl, ethyl, isopropyl) and to the 2-benzoyl deriv
