✦ Synopsis

Determination of the absolute configuration of several acyclic a-acyloxy-ketones, and d-ketobutanolides, in the presence of a chiral solvating agent, by low temperature and low concentration 1 H NMR analysis, is reported.

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
