The absolute configuration of (αR)-α,2'-dihydroxy-4,4'-dimethoxydihydrochalcone from the heartwood of Pterocarpus angolensis D.C. is established.Its structure is substantiated by synthesis and by photochemical conversion of its α-O-tosyl derivative into an α-tosyloxymethyldeoxybenzoin and hence to the α-methyldeoxybenzoin analogue.The photochemical step also leads, amongst others, to α-hydroxymethyldeoxybenzoin, β-hydroxydihydrochalcone, and 2-benzylbenzofuran-3-one analogues depending on the conditions the photolysis.
