Abstract
A new convenient route to enantiopure 2-coumarinyloxypropanals is described: Rosenmund reduction of ( R)- or ( S)-2-coumarinyloxypropanoyl chlorides afforded in good yields the corresponding 2-coumarinyloxypropanals. Their subsequent aldolic condensation with 3(2 H)-furanones, followed by dehydration, led to enantiopure geiparvarin analogues now being investigated as promising antitumoral compounds.
