A convenient, high yield, two step synthesis of 3-allylcoumarine and their benzo dsriuatives is described fmm 2-hydroxybenzaldehydes. The benzaldehydes (2a-j) on reaction with phosphorane 3 provide E-ethyl-α-allylcinmates (4a-j) in high yields. These esters (4a-j) on themal or photochemiml cyclisation give 3-allylcoumarines (6a-j) .
