deprotonation susceptibility, such as tetramic and tetronic acids, cyclic 1,3-diketones, and cycloalkanones. Application to the synthesis of bioactive, pyrrolizine-fused 4-quinolinone, penicinotam 3, resulted in the most brief and highest yielding totalsynthesis of the alkaloid in three steps and a 36% overall yield.

New 1-hydroxy-10-alkylacridin-9(10H)-one BF2-chelates absorb in the blue-green part of the electromagnetic spectrum and emit fluorescence with moderate quantum yields of 8–45% in toluene. The dyes show large Stokes shifts about 4300 cm−1, decay times between 5 ns and 15 ns in toluene and high photostabilities. Introduction of a fluorine atom into the acridone cycle results in an increase of the fluorescence
新的1-羟基-10-烷基ac啶9-9 (10 H)-1 BF 2螯合物在电磁光谱的蓝绿色部分吸收并发出荧光,在甲苯中的荧光量子产率为8–45%。染料在甲苯中显示出大的斯托克斯位移,约为4300 cm -1,衰减时间在5 ns到15 ns之间,并且具有高光稳定性。将氟原子引入a啶酮循环会导致荧光量子产率和衰减时间的增加,而固定在刚性聚合物基质(聚苯乙烯)中的寿命则进一步延长至18 ns。较大的斯托克斯位移和长的发射衰减时间使该染料类成为时间分辨成像和传感应用的有趣平台。
Rhodium(<scp>iii</scp>)-catalysed decarbonylative annulation through C–H activation: expedient access to aminoisocoumarins by weak coordination

日期:——
Rhodium-catalysed decarbonylative annulation of isatoic anhydrides with alkynes through C–H activation for the synthesis of aminoisocoumarins was developed. This enables the gram-scaletransformation to iodoisocoumarin which is a vital building block in transition-metal-catalysed cross couplings. These compounds exhibit blue-emitting luminescence properties.

A high throughput screening approach to the identification of selective cholecystokinin-2 receptor (CCK-2R) ligands resulted in the discovery of a novel series of antagonists, represented by 1-[2-[(2,1,3-benzothiadiazol-4-ylsulfonyl)amino]-5-chlorobenzoyl]-piperidine (1; CCK-2R, pK(I) = 6.4). Preliminary exploration of the structure-activity relationships around the anthranilic ring and the amide and
