Abstract

Synthesis of 10, 11-dihydro-, 10, 11, 14, 15-tetrahydro-, and 10, 11-dihydro-12- oxoleukotriene B4 compounds (2, 4, 5) was accomplished stereoselectively by using the nickel-catalyzed coupling reaction illustrated in Scheme 1. The C (1)-C (7) fragments, TBS ether 10a for 2 and 4 and ethyoxyethyl (EE) ether 10b for 5, were prepared in enantiomerically pure forms (> 99% ee) by a modified literature procedure (ref 11a). On ...
