Process for preparing tert-alkyl ester from carboxylic acid |
abstract |
A process for preparing a tert-alkyl carboxylic acidnester represented by the formula (III):n nwherein R 1 is an organic group; and each of R 2 and R 3 isnindependently an alkyl group having 1 to 4 carbon atoms,ncomprising reacting a carboxylic acid represented by thenformula (I):n R 1 -COOH nwherein R 1 is as defined above, with a vinylidene compoundnrepresented by the formula (II):n nwherein R 2 and R 3 are as defined above, in the presence ofna phosphorus halide. The tert-alkyl carboxylic acid esterncan be used as intermediates for pharmaceuticals such asnantibiotics. |
