    • We have done Noyori's reduction many times in the past without problems and, as reported in this manuscript, the reduction proceeded well for compounds 20, 25, 35 and only with (S)-BINAL-H for 30 leading to 31a. Astonishingly, we observed a transesterification during the reaction with (R)-BINAL-H with 30 leading to 31b ethyl ester instead of methyl ester. But the difference between a methyl ester and an ethyl ester is not important and 31b was nicely used anyway.
