Twelve heterocyclic aromatic acetals (1a-12a) have been synthesised and their reactions with Lewis acids, viz. boron trifluoride etherate (BTE) and stannic chloride (STC) have been studied.The acetals yield ethers, esters and aldehydes with BTE, but only esters and aldehydes with STC.Interestingly, pyridine-2-aldehyde acetal (12a), yields aldehyde alone, that too in low yield.Probable mechanisms have been suggested for the product formation.
