摘要: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-methylendioxy-benzaldehyde (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.

标题:Synthesis of difluoromethyl ethers and sulfides
发明人：HARTWIG JOHN; FIER PATRICK
权利人:UNIV CALIFORNIA
摘要:The synthesis of difluoromethyl ethers and sulfides with a simple, non-ozone-depleting reagent is described. The difluoromethylation of phenols with this reagent occurs at room temperature within minutes with exceptional functional group tolerance. The mild conditions makes possible tandem processes for the conversion of aryl boronic acids, aryl halides and arenes to difluoromethyl ethers. Mechanistic studies support a reaction pathway involving nucleophilic attack of the phenolate to difluorocarbene.
