The Preparation of Optically Active Δ2-Isoxazolines via Addition of Nitrile Oxides to Chiral Acryloyl Esters Bearing Cyclitols as Auxiliaries

Akiyama, Takahiko,Okada, Kohji,Ozaki, Shoichiro

, p. 5763 - 5766 (2007/10/02)

An acryloyl ester derived from (1L)-3-t-butyldiphenylsilyl-1,2:5,6-di-O-cyclohexylidene-chiro-inositol underwent 1,3-dipolar cycloaddition with nitrile oxide to give Δ2-isoxazolines of high diastereomeric excess (up to 90percent de).
