标题:在无金属条件下使用醚作为c1合成子轻度接触伯胺的n-甲酰化
摘要:已经开发了一种新的合成方案,用于在无金属反应条件下使用醚作为c1合成子来合成n-甲酰胺衍生物.该反应被提议通过ch官能化,Co裂解和cn键形成来进行.该方案适用于各种伯胺,可产生中等至非常好收率的n-甲酰胺.在用各种醚筛选后,选择1,4-二恶烷作为最佳的c1合成子.机理研究表明,该反应通过自由基途径进行.使用α-氨基酮时,形成的是α-烷基化产物,而不是甲酰化产物.通过在标准条件下用四甲基乙二胺(tmeda)代替二恶烷,也可得到中等收率的n-甲酰胺衍生物.

标题 :Efficient process for the synthesis of alkoxy substituted benzaldehydes
发明人：MOHAPATRA Manoj Kumar; BENDAPUDI Ramamohanrao; MENACHERRY Paul Vincent; PAUL VINCENT
权利人:ANTHEA AROMATICS PRIVATE LTD
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.
