Abstract
2-Methoxy- or ethoxy-4-propen-(1)-yl phenols are obtained in two steps by condensation of corresponding 2-alkoxy phenols with propionaldehyde in the presence of acidic catalysts followed by thermal cleavage of the condensation products in the presence of basic catalysts. The yields in this process are high, and the process is easy to carry out. The resulting compounds are used mainly as flavourings or starting materials for other flavourings.
