Abstract
The asymmetric synthesis of L-699,392 (1)[3-[[(1S)-[3 (E)-[2-(7-chloroquinolinyl) ethenyllphenyll-3-(acetylphenyl) propyl] thio]-2 (S)-methylpropanoic acid], a leukotriene antagonist, is accomplished in six steps starting from the monoaldehyde 2. The main framework of the molecule is formed via a Pd-catalyzed Heck reaction. The asymmetric center is introduced via the chiral reduction of the ketone 4 using optically active B- ...
