Both nonracemic 3-pyrrolines and 2,3-cis-2-vinyIaziridines have been synthesized selectively from common (Z)-allylic alcohols by simply changing the leaving group and the reaction conditions. Whereas treatment of (Z)-allylic mesylates with NaH yields exclusively 3-pyrrolines in high yields, exposure of allylic methyl carbonates to a catalytic amount of Pd(PPh3)4 affords 2,3-cw-2-vinylaziridines diastereoselectively in high yields. A simple synthesis of (5)-3,4-dehydroproline starting from (/?)-serine is also described. Thieme Stuttgart.
