Hydrogenation of optically active esters of furancarboxylic acid
- 17 Downloads
Optically active and racemic menthyl furoates were produced for the first time, and their constants were determined.
The kinetics of the hydrogenation of menthyl furoate on a Pd(OH)2/C catalyst was investigated. Hydrogenation leads primarily to the tetrahydro-product without intermediate formation of the di-hydro-product. The activation energy of the process is equal to 4.9 kcal/mole.
Asymmetrical synthesis was carried out in the furan series: it was shown that hydrogenation proceeds stereospecifically. The optical yield of tetrahydrofuryl alcohol is 20%.
