A convergent synthesis was developed for the production of the core structure of prostaglandin D2 receptor antagonists for the treatment of allergic rhinitis. The key steps in this synthesis were a highly diastereoselective alkylation of (+)-nopinone, a chemo- and stereoselective reduction of an oxime to an amine, and a well-controlled reduction of an aminoalkyne to a (Z)-olefin.

A general method for the monoalkylation of (+)-nopinone was developed for a variety of carbon and heteroatom electrophiles to afford the kinetically controlled product 2 with high diastereoselectivity (98% d.e.) and excellent yield (75-90%).
