Regio and diastereoselective synthesis of functionalized 2,3-dihydrofuro[3,2-c]coumarins via a one-pot three-component reaction
Altieri, Elisa,Cordaro, Massimiliano,Grassi, Giovanni,Risitano, Francesco,Scala, Angela
, p. 9493 - 9496 (2010)
An efficient and straightforward synthesis of furo[3,2-c]coumarins via the one-pot three-component condensation of aromatic aldehydes, 4-hydroxycoumarin and α-chloroketones in refluxing n-propanol is described. Pyridine or a mixture of AcOH and AcONH4 was used as a basic catalyst.
