By the use of a new axially chiral reagent, 2'-methoxy-l,l'-binaphthalene-2-carbohydroximoyl chloride (MBCC), chiral cyclic alkenes were stereoselectively derivatized into 4,5-dihydroisoxazoles. NOEs were observed between the protons of the reagent moiety and those of the alkene moiety in cycloadduc
Sutmnary: Absolute configurations of axially chiral biaryls with hydroxyl, amino, and carboxyl groups can be easily determined by pmr spectra using MTPA derivatives and shift reagents. Recently chiral biaryls have been successfully utilized in the field of asynetric synthesis\*. For example, virtual
