1,3-dipolar cycloaddition of difluoro(methylene)cyclopropanes with nitrones: Efficient synthesis of 3,3-difluorinated tetrahydropyridinols

Hang, Xiao-Chun,Chen, Qing-Yun,Xiao, Ji-Chang

body text, p. 1989 - 1992 (2009/04/07)

Difluoro-substituted spirocyclopropaneisoxazolidines were formed by 1,3-dipolar cycloaddition of difluoro(methylene)cyclopropanes (F 2MCPs) with nitrones in high yields. The [3+2]-cycloaddition reactions exhibited good regioselectivity and high
