Abstract
Primary and secondary allylic alcohols underwent a regioselective Mitsunobu reaction with readily accessible N-Boc ethyl oxamate to deliver the corresponding N-Boc allylic amines. Subsequent N-methylation and Boc deprotection without chromatography yielded the amine products as hydrochloride salts.
