Selenium-induced cyclization of O-allyl oximes as a synthetic route to N-alkyl isoxazolidines
摘要:
Phenylseleneyl bromide easily reacts with O-allyl oximes to afford cyclic iminium bromides which can be reduced in situ with sodium borohydride to produce substituted N-alkyl isoxazolidines in good yield.

Organoselenium-induced stereoselective cyclisation of O-allyl oximes: a new synthetic route to isoxazolidines
The organoselenium-induced ring-closure reactions of O-allyl oximes give cyclic iminium salts which react with water to afford isoxazolidines in good yield.
