Biosynthesis of [6]-gingerol, pungent principle of Zingiber officinale

Abstract
Evidence is adduced for a scheme of bio-synthesis for (S)-(+)-[6]-gingerol in Zingiber officinale Roscoe, in which dihydroferulate is built up from phenylalanine and participates in a new example of a ‘biological Claisen reaction’ with malonate and hexanoate; the β-diketone product is then reduced to [6]-gingerol.
