标 题:Synthesis of glycols via transfer hydrogenation of alpha-functional esters with alcohols
发明人：CHAKRABORTY SUMIT; HEMBRE ROBERT THOMAS
权利人:EASTMAN CHEM CO
摘要:A transfer hydrogenation process for forming vicinal diols by hydrogenating 1,2-dioxygenated organic compounds using alcohols as the reducing agent instead of the traditional H 2 gas. The transfer hydrogenation is carried out under milder conditions of temperature and pressure than is typical for ester hydrogenation with H 2 . The milder conditions of operation provide benefits, such as lower operating and capital costs for industrial scale production as well as savings in product purification due to the avoidance of by-products from exposure of reaction mixtures and products to high temperatures.

摘要:A process for preparing a β-lactam derivative having a hydrogen atom on the nitrogen atom of the β-lactam ring, which comprises reacting a β-lactam derivative having a mono- or diarylmethyl group on the nitrogen atom of the β-lactam ring with an acid or ceric ammonium nitrate to cleave the bond between the nitrogen atom and the mono- or diarylmethyl group; and novel β-lactam derivatives useful as intermediates for the synthesis of pharmaceutical agents.

摘要:The present invention is directed to a method for the synthesis of a bi-functional complex comprising a molecule part and an identifier oligonucleotide part identifying the molecule part. A part of the synthesis method according to the present invention is preferably conducted in one or more organic solvents when a nascent bi-functional complex comprising an optionally protected tag or oligonucleotide identifier is linked to a solid support, and another part of the synthesis method is preferably conducted under conditions suitable for enzymatic addition of an oligonucleotide tag to a nascent bi-functional complex in solution.
