The reaction of a racemic perhydroisoquinolene derivative 9 with the homochiral lithiumamide basse 3 in the presence of Me3SiCl in an regiodivergent fashion to give the two non-racemic regioisomeric enol silanes 10 and 11. Conversion of 10 into enone 15, an intermediate useful in the synthesis of the alkaloid (+)-yohimbine, was also possible.
