Conjugate addition of lithium N-tert-butyldimethylsilyloxy-N-(alpha-methylbenzyl)amide: asymmetric synthesis of beta(2,2,3)-trisubstituted amino acids
Conjugate addition of the homochiral ammonia equivalent lithium N-tert-butyldimethylsilyloxy-N-(α-methylbenzyl)amide to a range of α,β-unsaturated esters gives the corresponding β-amino esters in moderate to good levels of diastereoselectivity. O-Desilylation and cyclisation furnishes homochiral iso...
