Aziridination of vinylsilanes and vinylstannanes: a new synthesis of azirines
Abstract
Aziridination of vinylsilanes and vinylstannanes with the N-acetoxyaminoquinazolone (8) gave aziridines (1)–(7): caesium fluoride in dimethylformamide brought about elimination of trimethylsilyl and quinazolone groups from (1) and (2) to give the corresponding azirines.
