  • Patent number: 5675019
    Abstract: A process of preparing lactam derivatives of pilocarpine is disclosed. The process involves condensation of a dihydroxybutene and alkyl orthoester to form a lactone intermediate which is oxidized to trans-pilopic acid. This lactone ring is reacted with a benzylamine and the benzyl group removed with a novel dissolving metal reduction mixture to yield the key intermediate IV ##STR1## which can be elaborated to pilolactam through a known sequence of steps.
