Facile Synthesis of 3-Thioxo-3H-benzo[f]chromen-2-yl methanone and 3H-Benzo[f]chromene-3-one Under Solvent Free Condition

A facile, convenient, efficient and high yielding synthesis of a combinatorial library of coumarins has been developed by the condensation of readily available $\beta$-oxodithioesters and S,S-acetal with 2-hydroxy-1-naphthaldehyde in the presence of catalytic amount of $CuCl_2$ under solvent free co...
