专利号:US-6288244-B1 优先权日:1999-03-31 标 题 :Process for the preparation of 3, 4-dihydroxybutanoic acid and derivatives thereof from substituted pentose sugars 发明人:HOLLINGSWORTH RAWLE I 权利人:UNIV MICHIGAN STATE 摘要:A process for the preparation of 3,4-dihydroxybutanoic acid (I) and 3-hydroxy-γ-butyrolactone (V) thereof from a 3-leaving group substituted pentose source is described. In particular, the process relates to the synthesis of (R)-3,4-dihydroxybutanoic acid and (R)-3-hydroxy-γ-butyrolactone from a 3-leaving group substituted L-pentose sugars. The process uses a base and a peroxide to convert the pentose source to the chiral 3,4-dihydroxybutanoic acid compound. The chiral 3,4-dihydroxybutanoic acid can be further converted to 3-hydroxy-γ-butyrolactone by acidification. The chiral compound is useful as a chemical intermediate to the synthesis of various drugs and other products.
专利号:US-8772526-B2 优先权日:2009-12-21 标 题:Method for preparing dithiocarbamates in particular from polyols of the glycerol type 发明人:JEROME FRANCOIS; DE SOUSA RODOLPHE; BARRAULT JOEL; POUILLOUX YANNICK 权利人:JEROME FRANCOIS; DE SOUSA RODOLPHE; BARRAULT JOEL; POUILLOUX YANNICK; CENTRE NAT RECH SCIENT; UNIV POITIERS 摘要:The present invention concerns a method for the synthesis of glycerol dithiocarbamates or bis-dithiocarbamates (GDTCs) in which a reaction medium comprising (1) a carbonate selected from diethyl carbonate, dimethyl carbonate and ethylene or propylene carbonate associated with a glycerol type polyol in the presence of a basic catalyst or (2) a cyclic carbonate comprising five ring members, in a solvent medium, is supplemented with a primary or secondary amine in the presence of carbon disulphide, and the GDTC formed is recovered. In particular, a glycerol type polyol is brought into the presence of diethyl carbonate in the presence of a catalyst, then a primary or secondary amine is added to the reaction medium in the presence of carbon disulphide, and the GDTC formed is recovered. The invention can be used for one-step synthesis of glycerol dithiocarbamates directly from glycerol as the starting material and solvent. This method involves glycerol, diethyl carbonate, carbon disulphide (CS 2 ) and a primary or secondary amine to produce glycerol dithiocarbamates; the glycerol/NaOH phase can be recycled 6 times without a noticeable drop in yield; the ethyl acetate is also recycled after each extraction.
