ofnitriles.Amides were obtained through partial hydrolysis of nitriles,using two different energy sources,traditional heating with solvent reflux and ultrasound.The reaction was performed at micro and semi-micro scales and at different reaction time with both energy sources.Yield was determined through ...
(酯,酰胺,腈类的部分还原)Partial Reduction of Esters, Amides nad Nitriles with Metal Hydride 羰基酸衍生物 →醛 概要 酯,酰胺,腈类在适当的氢化金属还原剂的存在下,低温反应可以还原成醛。经常使用的还原剂有DIBAL、Red-Al等。酯基相对于腈类化合物来说,要被还原后停留在醛的阶段,更加不容易。使用2当量以...
Catalytic hydrogenation or transfer hydrogenation of quinolines was thought to be a direct strategy to access dihydroquinolines. However, the challenge is to control the chemoselectivity and regioselectivity. Here we report an efficient partial transfer hydrogenation system operated by a cobalt-amido cooper...
The conversion of the cyano group of formula B to the —CO2R2 group of formula A is achieved by hydrolysis at step S-5. In certain embodiments, step S-5 is performed in an alcoholic solvent such that a compound of formula A is formed wherein R2 forms the corresponding ester. According...
