Title: Hydrogenation process
Inventor: HILES ANDREW G
IPC: C07B31/00
Filed: 1986-09-11
Granted: 1995-05-15
Abstract: A continuous multi-stage hydrogenation process is described.This is effected in at least three catalytic stages connected in series. All stages up to and including the penultimate stage are operated adiabatically and in the vapour phase. Aldehyde (or other unsaturated organic compound) is fed to all stages ut to and including the penultimate stage. The rate of supply of the aldehyde or other unsaturated organic compound to the penultimate stage is controlled in relation to the catalyst volume in the penultimate catalytic stage so that the degree of hydrogenation in that stage is less than 100 %. The remaining chemically unsaturated material in the product mixture from the penultimate stage is hydrogenated, after cooling that product mixture, in the final catalytic stage to produce a substantially completely hydrogenated product mixture. In this way the dwell time of the reactants and product(s) at "hot spot" temperatures is minimised, thus reducing byproduct formation.

Thus, benzyloxycarbonylmethylidenetriphenylphosforan was reacted with formylacetate in toluene at 80-120↿C for 1-6 hr to give 87% corresp. propenedicarboxylate, which was reacted with anisole and trifluoroacetate in CH2Cl2 for 2hr to give 89% 22-(2- benzyloxycarbonylaminothiazol-4-yl)-4benzyloxycarbony-2-butenic acid.  (I) are useful as antibacterial agent.
