权利人:SANOFI S A AND INST NATIONAL D
摘要:The process described makes it possible to obtain optically pure 4-amino-3-hydroxycarboxylic acids by means of a series of stereoselective steps. The starting material is an alpha-amino acid in the L or D configuration, with which Meldrum's acid is reacted. The resulting pyrrolone derivative is reduced prior to opening of the pyrrolidine ring. The invention also relates to the new products obtained by the said process and to the pyrrolone derivatives obtained as intermediates.

摘要:The present invention provides various processes for producing methanol and ethanol, preferably in a mixed alcohol stream. In one embodiment, the invention includes directing syngas to a synthesis zone wherein the syngas contacts a methanol synthesis catalyst and an ethanol synthesis catalyst (either a homologation catalyst or a fuel alcohol synthesis catalyst) under conditions effective to form methanol and ethanol. The methanol and ethanol, in a desired ratio, are directed to an oxygenate to olefin reaction system for conversion thereof to ethylene and propylene in a desired ratio. The invention also relates to processes for varying the weight ratio of ethylene to propylene formed in an oxygenate to olefin reaction system.
