专利号:US-8710268-B2 优先权日:2007-07-31 标题:Method for the hydrolysis of substituted formylamines into substituted amines 发明人:BOBYLEV MIKHAIL 权利人:BOBYLEV MIKHAIL 摘要:An improved method for the synthesis of substituted formylamines and substituted amines via an accelerated Leuckart reaction. The Leuckart reaction is accelerated by reacting formamide or N-alkylformamide and formic acid with an aldehyde or a ketone at a preferred molar ratio that accelerates the reaction. The improved method is applicable to various substituted aldehydes and ketones, including substituted benzaldehydes. An accelerated method for the hydrolysis of substituted formylamines into substituted amines using acid or base and a solvent at an elevated temperature. The improved method is useful for the accelerated synthesis of agrochemicals and pharmaceuticals such as vanillylamine, amphetamine and its analogs, and formamide fungicides.
专利号:US-2017266353-A1 优先权日:2014-05-13 标 题:Bioadhesive compounds and methods of synthesis and use 发明人:MURPHY JOHN L; RADANO CHRISTOPHER P; DALSIN JEFFREY L; KOEPSEL JUSTIN T 权利人:DSM IP ASSETS BV 摘要:Synthesis methods for creating polymeric compounds comprising phenyl derivatives (PD), or PDp i.e., polymers modified with PD, with desired surface active effects are described. The polymer backbone of PDp has structural or performance features that can be tailored to control physical properties of PDp, allowing it to be useful for different applications i.e., tissue adhesives or sealants, adhesion promoting coatings, and antifouling coatings.
