In one embodiment, there is also provide a method of preparing a compound of formula (Ia), the method including conducting a cyclization reaction of a compound of formula (III) to obtain a compound of formula (IV), wherein conducting the cyclization reaction comprises conducting a Michael reaction in the presence of a Lewis acid.
专利号:US-5110929-A 优先权日:1986-08-07 标题 :Process for the preparation of N-alkylated quaternary nitrogen containing aromatic heterocycles 发明人:PARADIES HENRICH H 权利人:MEDICE CHAM PHARM FABRIK PUTTE 摘要:The synthesis of 4-, 4-(1,1)-and 3,5-substituted N-alkyl-pyridinium salts as well as of 2-carboxamide substituted N(1,4)diazinium compounds are described. The N-surfactants obtained have a small critical micelle concentration (CMC) of 10-5 -10-7 Mol/Liter. These surfactants produce micells of different size and form depending on the nature of the anions. 4-(1,1)-substituted and 3,5-substituted N-alkyl-pyridinium components are capable of forming vesicles in equeous solutions of different forms and sizes. The N-surfactants synthesized can be used as pharmaceuticals.
专利号:US-8673885-B1 优先权日:2010-07-25 标 题 :Compounds for the protection of sulfur containing linkers in nucleic acid synthesis 发明人:DUFF ROBERT 权利人:DUFF ROBERT 摘要:Aromatic and alkyl thiocarbonates with and without a neighboring group that participates in the hydrolysis of a thiocarbonate are described. The aromatic or alkyl thiocarbonates can be used for the protection of sulfur during oligonucleotide synthesis. Their facile processes of manufacture and methods of using the same are provided.
