  • Conjugate addition
    Patent number: 3935207
    Abstract: Organic compounds are prepared by a novel method of conjugate addition in which a donor compound including a carbanion derived from an activated methylidyne group is treated with an acceptor compound including a carbon-carbon unsaturated bond conjugated with an onium ion derived from a polar functional group. The method has particular application as a step in the production of novel intermediates and novel pharmacologically active compounds as disclosed in the Applicants' co-pending application of even date.
