Biogenesis of Stilbenolignans

The extension of a cinnamoyl-CoA chain (126) with malonate leads to the polyke-tide 127, which may be folded differently, depending on the enzymes present in the plant (Fig. 32). Stilbene synthase, for example, converts the polyketide into a stilbene (171) through an aldol-type condensation (86).
