摘要:A multidentate phosphite ligand is used in the catalytic synthesis of adiponitrile. The ligand is represented by the following general formula (I). The method of catalytic synthesis of adiponitrile comprises primary hydrocyanation, isomerization, and secondary hydrocyanation reactions, wherein the catalyst adopted each comprises a phosphite ligand-nickel complex composed of a nickel precursor and a multidentate phosphite ligand. The ligand molecule has a higher electron cloud density, and the phosphorus content capable of participating in coordination in the ligand molecule per unit mass is higher, so that the catalytic activity of the catalyst is improved, and the amount of the catalyst is reduced.

摘要:The compounds of general formula II are new and represent important intermediates in the synthesis of tapentadol. In the synthesis of tapentadol of formula I and its pharmaceutically acceptable salts, O-protected (2R,3R)-acids of general formula II, in step A, are reacted in an inert organic solvent with an activating agent, optionally in presence of a catalyst or a base; in step B, the obtained compounds of general formula V, wherein R has the above mentioned meaning and X stands for chlorine or alkoxycarbonyloxyl group O-CO-OR 1 or pivaloyloxyl O-CO-t-Bu group, wherein R 1 is methyl or ethyl, are reacted with dimethylamine or its salts optionally in presence of a base; in step C, the obtained N, N-dimethylamides of general formula VI, wherein R has the above mentioned meaning, are reduced by means of hydride agents in a suitable solvent; in step D, the produced alkeneamines of general formula VII, wherein R has the above mentioned meaning, are hydrogenated on a metal catalysts in a suitable solvent; and, finally, in step E, the produced alkaneamines of general formula VIII, wherein R has the above mentioned meaning, are O-dealkylated by means of dealkylating agents, and, if required, the obtained tapentadol is converted by the action of a pharmaceutically acceptable acid to respective salts, e.g. hydrochloride.

标题 :One-pot synthesis of anhydropentitol mono- and diethers
发明人:STENSRUD KENNETH
权利人:ARCHER DANIELS MIDLAND CO
摘要:A process for preparing anhydropentitol mono- and diethers from C 5 sugar alcohols is described. The process involves performing in a single reaction vessel consolidated reactions that a) cyclize dehydratively a linear C 5 sugar alcohol and b) etherify a resulting anhydropentitol. Each of the reactions is catalyzed by a very low amount of a water-tolerant Lewis acid catalyst relative to the starting sugar-alcohol. Depending on the reaction conditions, the synthesis method is efficient, selective and affords good yields of mono- and diethers. The anhydropentiol ethers can serve as renewable substitute precursors of petroleum incumbents for use in the making of surfactants and plasticizers.
