Diastereoselectivity in 1,3-dipolar cycloaddition reactions of alpha-methylene lactone derivatives
Original language description
Alpha-methylene lactones added stereoselectively various kinds of 1,3-dipolar compounds. Spiro pyrrolidines and spiro pyrrolizidines were prepared by addition of azomethin ylides generated from sarcosin and prolin resp. Cycloaddition of a photochemicallygenerated nitril ylide showed an unusual exo-selectivity. Alpha-methylene-gamma-lactone with a bulky substituent (OBO) in gamma position, which was prepared as a single enantiomer from L-glutamic acid, added 1,3-dipolar compounds in anti-manner almost exclusively.
