Abstract
The range of natural peltogynoid-type chalcone, flavonol, and dihydroflavonol analogues is extended by the recognition of carnein, β-photomethylquercitin, and (+)-2,3-trans-crombeone in the purple heartwood of Acacia carnei. The first synthesis of a 2,3-trans-peltogynone, crombeone tetramethyl ether, is effected and its catalytic reduction leads to a 2,3-trans-3,4-cis-peltogynol analogue. Crombeone itself is subject to a variety of methylene insertion reactions with diazomethane.This publication has 1 reference indexed in Scilit:
