Oxazinanones as chiral auxiliaries: synthesis and evaluation in enolate alkylations and aldol reactions.
Homochiral beta-amino esters (prepared on multigram scale by lithium amide conjugate addition) are readily transformed into oxazinanones. N-acyl derivatives of oxazinanones undergo stereoselective enolate alkylation reactions, with higher stereoselectivities observed for the enolate alkylation of (R...
