摘要:A method for a synthesis of a polymer containing multiple epoxy groups includes steps of: under protection of nitrogen or argon, with a photosensitive free radical initiator under an ultraviolet light irradiation, initiating a mixture of a dithiol compound and alkynyl glycidyl ether or other alkynyl-containing compounds to proceed a thiol-yne polymerization, so as to obtain the polymer. The number of the epoxy groups is able to be adjusted through changing a type of a dithiol monomer, a mixing ratio of the dithiol monomer, and a mixing ratio between the alkynyl glycidyl ether and other alkynyl compounds. The present invention has advantages of: fast reaction, convenient process, easy post-processing, a large number of the epoxy groups, and adjustable and controllable content. The obtained polymer has a wide potential application in fields of coating, adhesive, ink, encapsulating material, resin for composite material, additive, high performance material, function material, and so on.

摘要:The present invention is based on the discovery that 2-deoxyribose-5-phosphate aldolase (DERA, EC 4.1.2.4) and variants thereof can be used to catalyze sequential asymmetric aldol reactions between a wide variety of donor and acceptor aldehydes. The reaction products typically contain at least two new stereogenic centers and can be produced in enantiomerically pure form. As such, DERA catalyzed asymmetric aldol chemistry can be exploited to produce synthons for the synthesis of a variety of bioactive molecules.

摘要:This invention pertains to novel methods of synthesizing fludarabine, fludarabine phosphate and related nucleoside pharmacologic agents utilizing 6-azido-2-fluoropurine as a novel intermediate. n In particular this invention pertains to a synthesis of fludarabine where the relatively low yield fluorination step is done before the costly coupling step.
