专利号:US-6274383-B1 优先权日:1997-12-15 标题:Methods for synthesizing libraries of dihydro-quinazolinones 发明人:GAO YUN 权利人:SEPRACOR INC 摘要:Synthetic methods for solution and solid-phase synthesis of combinatorial libraries of dihydro-quinazolinones, including synthesis of 2,3-dihydro-3-alkoxy-4(1H)-quinazolinones or 2,3-dihydro-3-hydroxy-4(1H)-quinazolinones via the Lewis-acid catalyzed reaction of an appropriate 2-aminobenzamide with an aldehyde at ambient temperature performed on a solid support or in solution.
专利号:US-5741845-A 优先权日:1991-07-11 标 题:Process for production of azo macroinitiators for the synthesis of block copolymers and of aqueous block copolymer dispersions and emulsions and the use thereof 发明人:FRINGS RAINER B; KOMAZAKI SHIGERU; GRAHE GERWALD F 权利人:DAINIPPON INK & CHEMICALS 摘要:The invention concerns a process for the production of block copolymers or aqueous dispersions and emulsions thereof, whereby azo macroinitiators are reacted with radical-polymerizable monomers or a mixture of several radical-polymerizable monomers. The azo macroinitiators are obtained by reacting simple reactive azo compounds with prepolymers with a molecular weight between 400 and 20000, which possess at least 2 functional groups, e.g. polyurethanes or polyesters. n The aqueous block copolymer dispersions and emulsions produced according to the invention are suitable for use for the production of paints, adhesives etc.
专利号:US-9068192-B2 优先权日:2009-01-28 标 题:Compositions and methods for conversion of aldehydes to alkanes 发明人:ZENG WEIQING; HE SHENG YANG 权利人:ZENG WEIQING; HE SHENG YANG; UNIV MICHIGAN STATE 摘要:The invention provides the discovery that SCD2 (Susceptible to Coronatine-Deficient Pst DC3118-2) protein converts aldehydes to alkanes, thereby changing the composition and/or amount of synthesized waxes. The invention additionally provides homologs, orthologs and paralogs of SCD2 protein, and nucleotide sequences encoding these proteins. Also provided are expression vectors, transgenic cells, transgenic plants, transgenic seeds, methods for altering alkane production in cells, methods for identifying the function of a nucleotide sequence in the synthesis of plant surface wax, and methods for identifying plant tissue that has an altered surface wax composition. The invention's compositions and methods are useful for altering the amount and/or composition of wax produced by cells, including plants and seeds, that have been transformed with the invention's sequences.
