Selective deprotection strategies to N-(alpha-methylbenzyl)-beta-amino esters and derived beta lactams
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 these deprotection methods, lithium (α-methylb...
