Abstract
Four new chiral δ-substituted allylic trichloroacetimidates have been synthesised to probe the origin of the high diastereoselectivity observed for the MOM-ether directed palladium (II)- catalysed aza-Claisen rearrangement. Rearrangement of these compounds has not only provided strong evidence for this directing effect but also that during the rearrangement both oxygen atoms from the MOM-ether are involved in coordinating to and directing the ...
