Selective deprotection strategies to N-(α-methylbenzyl)-β-amino esters and derived β-lactams

Davies, Stephen G.,Ichihara, Osamu

, p. 6045 - 6048 (1998)

A variety of N,N-diprotected β-amino esters, prepared by highly diastereoselective conjugate addition of chiral lithium amides, were selectively mono-deprotected under either reductive (hydrogenolysis) or oxidative (DDQ or CAN) conditions. Combined with t
