TY - JOUR ID - 365652 AU - Častulík, Jakub - Melša, Petr - Mazal, Ctibor PY - 2001 TI - Diastereoselectivity in 1,3-dipolar cycloaddition reactions of alpha-methylene lactone derivatives PB - Institute of Chemical Technology, Prague and Czech Chemical Society CY - Prague SN - 8070804270 KW - Stereoselectivity KW - Methylene Lactones KW - 1;3-Dipolar Cycloaddition N2 - 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 photochemically generated 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.
