Abstract
An efficient protocol for the benzylation or allylation of amides using the corresponding benzyl or allyl chlorides as electrophiles under basic conditions with commercially available 5mol% of [Cu (OH) TMEDA] 2Cl2 as catalyst was developed. Under these conditions, unprotected amino acids were benzylated without any racemization.
