A novel phosphine-catalysed, one-pot domino approach for the annulation of 2-formylphenyl alkynoates with activated methylene compounds to construct various cyclopentene-fused dihydrocoumarins is reported. This developed strategy provides a facile and efficient approach for the synthesis of structurally complex coumarins from inexpensive and readily available alkynoates.

Chemical Equation Presented High chemoselectivity for the synthesis of two kinds of substituted coumarins controlled by the counteranions of the cationic palladium catalysts is described. The asymmetric version of the reaction for the synthesis of 3-alkylidene dihydrocoumarins is realized with high enantioselectivity
