PROCESS FOR THE HYDROGENATION OF ESTERS OF ALPHA-SUBSTITUTED CARBOXYLIC ACIDS
There is provided a process for the hydrogenation of esters of alpha-substituted carboxylic acids which comprises reacting an ester of an alpha-substituted carboxylic acid with hydrogen in the presence of a catalyst under substantially homogeneous supercritical conditions. Preferably, the ester of an alpha-substituted carboxylic acids is an ester of formula (1): wherein: R1 and R2are each independently an optionally substituted hydrocarbyl group or an optionally substituted heterocyclic group; and Y is a heteroatom or an optionally substituted heteroatom group. More preferably, the ester of an alpha-substituted is carboxylic acids is an ester of formula (2): wherein: R3 is an optionally substituted hydrocarbyl group or an optionally substituted heterocyclic group; R4and R5 are each independently hydrogen, an optionally substituted hydrocarbyl group or an optionally substituted heterocyclic group; Y is a heteroatom or an optionally substituted heteroatom group; Q is a functional group; and n 1. Most preferably, the ester of an alpha-substituted carboxylic acids is an ester of formula (3): wherein: R3 and R6 are each independently an optionally substituted hydrocarbyl group or an optionally substituted heterocyclic group; R4 and R5 are each independently hydrogen, an optionally substituted hydrocarbyl group or an optionally substituted heterocyclic group; Y is a heteroatom or an optionally substituted heteroatom group; and n 1.
Therefore, this conceptually novel strategy might open impressive avenues to establish green and sustainable chemistry platforms.In my other articles, you can also check out more blogs about4254-15-3.Synthetic Route of 4254-15-3
