25 - 030Regio- and Diastereoselective Cycloaddition of N-Methyl NitronesDerived from 3-(Allylamino)propionaldehydes. — High degree ofstereocontrol can be observed in cycloaddition reactions of N-methyl nitrones [cf.(III)] derived from 3-allylaminopropionaldehydes. Best results are achieved inreactions of nitrones bearing a methyl group at the 3-position. — (TANAKA,MASAYUKI; HIKATA, JUN; YAMAMOTO, HIDETOSHI; NOGUCHI,MICHIHIKO; Heterocycles 55 (2001) 2, 223-226; Dep.
