Microwave-induced protection and deprotection of 4-oxo-(4H)-1-benzopyran-3-carbaidehydes catalysed by Envirocat EPZ10 (R)

An efficient, solvent-free and chemoselective procedure for the synthesis of acylals and their deprotection to 4-oxo-(4H-)1-benzopyran-3-carbaldehydes catalysed by reusable Envirocat EPZ10(R) under microwave irradiation has been carried out in good yield.
