Stereo- and regioselectivity in nitrile oxide cycloaddition reactions to norethisterone acetate as dipolarophile
{{output}}
Benzo- and anthracenenitrile oxides undergo 1,3-dipolar cycloaddition reactions with 17 α- acetate norethisterone affording the expected isoxazoline and isoxazoles derivatives in good yields and as single regioisomers. The structures of all the new compounds ... ...
