The present invention relates to the synthesis of alkoxy substituted benzaldehydes obtained from the corresponding alkoxy substituted benzenes. Alkoxy substituted benzaldehydes are products of broad commercial interest and are used as end products and intermediates in flavor and fragrance applications and pharmaceutical ingredients. For example, 3,4-methylendioxybenzaldehyde (also known as heliotropin or piperonal) is used widely both as a end product and intermediate for the above mentioned applications. Other examples include 3,4-dimethoxybenzaldehyde, 3,4,5- trimethoxybenzaldehyde and 3,4-ethylenedioxybenzene which are intermediates in the synthesis of active pharmaceutical intermediates.
本发明涉及从相应的烷氧基取代苯醚合成的烷氧基取代苯甲醛。烷氧基取代苯甲醛是具有广泛商业兴趣的产品,用作风味和香料应用以及药用成分的终产品和中间体。例如,3,4-亚甲二氧基苯甲醛(也称为香豆酮或异香豆酮)被广泛用作上述应用的终产品和中间体。其他例子包括3,4-二甲氧基苯甲醛、3,4,5-三甲氧基苯甲醛和3,4-乙二氧基苯,它们是合成活性药用中间体的中间体。
