摘要

An asymmetric synthesis was developed for the production of a prostaglandin D(2) receptor antagonist for the treatment of allergic rhinitis. The stereogenic center was set using asymmetric allylic alkylation chemistry, and the core of the structure was constructed via Pd-catalyzed N-cyclization/Heck methodology. The synthesis relies on a late stage indoline oxidation which does not racemize the product.
