    • Interestingly, by the procedure described a mixture of 21a and 21b in a ratio of 18:1 was obtained. Upon sequential treatment of this mixture with n-BuLi and water the ratio of the isomers changed to 1:18. It seems that 21a is the product of a kinetically controlled reduction of 14a and that 21b is the thermodynamically more stable isomer, possibly because of an intramolecular hydrogen bond. The configuration at C-1 of 21a and 21b was determined by NOE experiments.
