Abstract

An efficient one-pot multicomponent condensation of β-naphthol, aldehydes, and β-oxobenzenepropane (dithioates) is developed using catalytic amount of B3.OEt2 under solvent-free conditions for the synthesis of several 1Hnaphtho[ 2,1-b]pyran derivatives.

Keywords: 1H-naphtho[2, 1-b]pyrans, BF3.Et2O, multicomponent reaction, solvent-free, β-oxodithioesters.
