process for the production of diels - alder addukten of sterin - 5.7 - serve with catalytic unsaturated fatty acids

摘要

An improved process and composition are disclosed for isolation of steroids containing a 5,7-diene functionality from a sterol mixture that comprises formation of a Diels-Alder reaction product of the ster-5,7-dienol in the presence of at least a catalytic amount of an ethylenically unsaturated C12-C24 fatty carboxylic acid.
