Abstract

We next explored the use of this transient protection/Mitsunobu alkylation sequence for synthesis of the 06-cyanoethyl derivative 5a. In this case the reaction of 3- hydroxypropionitrile with lb under conditions identical to those used for synthesis of 4b gave none of the expected product. Reactions using 2-(phenylsulfony1) ethanol were also unsuccessful. Apparently for these alcohols the Mitsunobu intermediate (6) undergoes ...
