The rearrangement of a range of N-benzyl-O-allylhydroxylamines to the corresponding N-allylhydroxylamines upon treatment with n-BuLi in THF, followed by reduction to the corresponding N-allylamines, is described. Mechanistic studies of the transforma

Chiral auxiliaries and templates are effective tools for the asymmetric synthesis of homochiral molecules.1 Most chiral auxiliaries are small heterocyclic compounds which rely on sterically demanding functional groups to control the conformation of t

Alkylation studies on the enolate of N -methyl morpholinone 7 clearly reveal that the observed cis -selectivity is consistent with a chiral relay system operating to invert the stereochemical information of the auxiliary's C 5 stereogenic centre.

High levels of diastereoselectivity are observed for benzylation of the lithium enolates of (S)-N,N′-bis-para-methoxybenzyl-3-iso-propyl- piperazine-2,5-dione, (S)-N(1)-para-methoxybenzyl-N(4)-methyl-3-iso-propyl- piperazine-2,5-dione and (S)-N(1)-
