A generalmethod 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%).
A compound selected from one of the following:
or a salt, solvate, chemically protected form or prodrug thereof, and its use in treating conditions alleviated by agonism of an EP
2
receptor.
