ABSTRACT:
Optically active tert-alkyl 7-2(oxo-5-carbonyloxypyrrolidinyl)heptanoates and their preparation by reaction of racemic tert-alkyl 7-(2-oxo-5-carboxypyrrolidinyl)heptanoate with an optically active amine to form resolved d or l amine salts which are then reacted with acid to form resolved acid intermediates. Esterification of these acid intermediates produces resolved d or l esters which are useful to make optically active 8-azaprostanoids having biological activity.
