Diphenylboryl trifluoromethanesulfonate

Higher diastereoselectivities in ring opening of bicyclic anhydrides are obtained through their diphenylboryl trifluoromethanesulfonate catalyzed reaction with (7 )-l-diphenylboryloxy-2-methoxy-l-phenylethane in toluene at 0CC98. [Pg.624]

The reaction with acetals does not always need the acetal itself to be synthesized it can be made in the same flask by mixing the allylsilane, the aldehyde, the silyl ether of the alcohol, and a catalytic amount of an acid such as diphenylboryl trifluoro-methanesulfonate, trimethylsilyl trifluoromethanesulfonate, or fluorosulfuric acid. ... [Pg.14]
