摘要:研究了有机-无机吡啶鎓溴化铅[(Pyh)Pbbr 3 ]和碘化物[(Pyh)Pbi 3 ]化合物的光致发光特性随温度的变化.无机子结构由 Pbx 6八面体的共面链组成.化合物的漫反射光谱显示出低能量吸收特征,与从 Pbx 3链到吡啶鎓阳离子的电荷转移跃迁一致.两种化合物在室温下均表现出极弱的发光,冷却至 77 K 时发光强度大大增强.两种化合物的宽广,无特征的低能量发射 ( λ Em > 600 Nm) 具有较大的斯托克斯位移 [(Pyh)Pbbr 3 为 1.1 Ev,(Pyh)Pbbr 3为 0.46 (Pyh)Pbi 3 ] 的 Ev 被指定为来自无机链上自俘获激子的跃迁,而 (Pyh)Pbbr 3 ( λ Em = 450 Nm) 中较高能量的发射被指定为来自自由激子态的发光.对温度依赖性发光强度测量数据的分析给出了(Pyh)Pbbr 3和 (Pyh)Pbi 3中自陷激子非辐射衰变的活化能

标 题:Process for synthesis of optically pure prostaglandin E2 and analogs thereof
发明人：FUCHS PHILLIP L
权利人:PURDUE RESEARCH FOUNDATION
摘要:The invention comprises a multi-step synthesis of l(-) prostaglandin E 2 . The special features of the synthesis include: (1) a triply-convergent conjugate-addition and alkylation reaction involving the 1,4-addition of a chiral vinyl lithium reagent to a chiral vinylsulfone to produce a sulfone-stabilized anion. This anion is alkylated in situ to produce the basic prostaglandin skeleton structure, which is then subjected to (2) an efficient peracid oxidation of a secondary amine to a β-silyloxy oxime; and (3) an alkali-catalyzed 1,4-elimination of an α-sulfonyl oxime to produce a vinyl nitroso intermediate. This intermediate is treated with borohydride to give a stereospecific 1,4-reduction which yields the bis-silyloxy oxime of l(-)PGE 2 . Hydrolysis of the oxime, with concurrent cleavage of the silyloxy protecting groups, affords l(-)PGE 2 .

标题 :Synthesis of tetracyclines and analogues thereof

摘要:The tetracycline class of antibiotics has played a major role in the treatment of infectious diseases for the past 50 years. However, the increased use of the tetracyclines in human and veterinary medicine has led to resistance among many organisms previously susceptible to tetracycline antibiotics. The modular synthesis of tetracyclines and tetracycline analogs described provides an efficient and enantioselective route to a variety of tetracycline analogs and polycyclines previously inaccessible via earlier tetracycline syntheses and semi-synthetic methods. These analogs may be used as anti-microbial agents or anti-proliferative agents in the treatment of diseases of humans or other animals.

摘要:A process for one pot synthesis of citalopram is disclosed. The process comprises subjecting 5-cyano phthalide to Grignard reduction followed cyclization and followed by C-alkylation reaction to obtain citalopram without isolation and purification of any intermediates. In another embodiment, 5-cyano phthalide is subjected to sequential Grignard reactions followed by cyclization to obtain citalopram without isolation and purification of any intermediate stages.
