Herein, we communicate a one-pot catalytic asymmetric synthetic method involving a broad range of saturated ethers and diverse carboxylic acid derivatives as starting materials. The one-pot synthetic method was designed as follow: saturated ether reacting with a combination of a protic additive and ...
Removal of the oxide from the metal surface is an acid-base reaction in which salt is formed (as presented by Eqs. (1) and (2)) that evaporates and may have left residue depending on the type of carboxylic acid. (1)Cu2O+RCOOH→CuRCOO2+Cu+H2O (2)Sn+CuRCOO2→SnRCOO2+Cu In a ...
Synthesis of Cefdinir from 7-Amino-3-vinyl Cephem-4-carboxylic Acid Using N-Methyl Morpholine as Base In this paper, synthesis of cefdinir (I) from 7-amino-3-vinyl cephem-4-carboxylic acid (V) is reported by reacting with 2-mercapto benzothiazolyl (Z)-2-(2-... D Muralikrishna,A ...
The process comprises the step of reacting a carboxylic acid with an olefin to yield a corresponding carboxylic acid ester or reacting an alcohol with an olefin to yield a corresponding ether compound. In the process, a catalyst ... 崔 準哲,高野 一史,安田 弘之,... 被引量: 0发表: 2007...
