Synthesis of phenyl analog of retinoic acid methyl ester proceeding from 3-(bromomethyl)but-3-enal diethylacetal

详细

Aromatic analog of retinoic acid methyl ester was prepared using a convenient prenylating agent, 3-(bromomethyl)but-3-enal diethylacetal, and Barbier reaction in the key stage of building up the carbon chain of target molecules. A version is offered of the synthesis of methylidene analog of aromatic retinoic acid.
