Synthesis of (±)-peltogynol trimethyl ether and its cis,cis-stereoisomer
Abstract
Racemic peltogynol trimethyl ether has been synthesised from (±)-peltogynone trimethyl ether, obtained indirectly from 2′-hydroxymethyl-7,4′,5′-tri-methoxyflavonol; the flavonol has also been converted into the racemic cis,cis-isomer of peltogynol trimethyl ether.
