Abstract

IC I t for both compounds. The isomers were formed in a ratio of 65/35 f 5% in several preparations. Since the conditions used were identical with those we have employed previously for trans-acetalizations of similar compounds, we believe that this ratio reflects the equilibrium position (see below). There does not appear to be an unambiguous method6 (other than, in principle, X-ray crystallographic analysis or optical isomer resolution) to ...
