标题:杂芳族化合物合成的闭环复分解:评估吡啶和哒嗪的路线
摘要:闭环烯烃复分解(rcm)已用于稠密和不同取代的吡啶和哒嗪骨架的有效合成.研发了合适的复分解前体的途径,并探讨了复分解步骤的范围.复分解产物通过消除合适的离去基团而充当目标杂芳族结构的前体,这还通过充当氮上的保护基团而促进了较早的步骤.在芳构化之前和之后,复分解产物的进一步功能化都是可能的.最终结果是强有力的从头合成高度取代的杂芳族骨架的策略.

标 题 :PH-sensitive polymer containing sulfonamide and its synthesis method
发明人：BAE YOU HAN; PARK SANG YEOB
权利人:KWANGJU INST SCI & TECH
摘要:There are disclosed pH-sensitive polymers containing sulfonamide groups, which can be changed in physical properties, such as swellability and solubility, depending on pH and which can be applied for a drug-delivery system, bio-material, sensor, etc, and a preparation method therefor. The pH-sensitive polymers are prepared by introduction of sulfonamide groups, various in pKa, to hydrophilic groups of polymers either through coupling to the hydrophilic groups, such as acrylamide, N,N-dimethylacrylamide, acrylic acid, N-isopropylacrylamide, etc, of polymers or copolymerization with other polymerizable monomers. These pH-sensitive polymers may have a structure of linear polymer, grafted copolymer, hydrogel or interpenetrating network polymer.
