and evaluated a series of compounds at the human histamineH 4 receptor (H 4R) from which 2-(4-methyl-piperazin-1-yl)-quinoxaline ( 3) was identified as a new lead structure for H 4R ligands. Exploration of the structure-activity relationship (SAR) of this scaffold led to the identification of 6,7-dichloro 3-(4-methylpiperazin-1-yl)quinoxalin-2(1 H)-one (VUF 10214, 57) and 2-benzyl-3-(4-methyl-pip
We have developed a versatile and efficient method for copper-catalyzed synthesis of both 2-amino-4(3H)-quinazolinone and 2-aminoquinazoline derivatives. The protocol uses readily available substituted 2-halobenzoic acids, 2-bromobenzaldehyde, 2-bromophenyl ketones and guanidines as the starting materials, inexpensive copper(I) iodide as the catalyst, and the method has important application values

nucleophiles. Utilizing the Phoenix Flow Reactor™ in parallel with Design-of-Experiment software enabled rapid optimization of the SNAr protocol. This protocol facilitated efficient synthesis of a broad range of 2-aminoquinazolines, and was extended to 2-aminoquinoxalines and 2-aminobenzimidazoles.
我们在此报告的高温和高压的连续流协议来进行亲核芳香取代(S Ñ与氮亲核试剂的杂环的Ar)。通过将Phoenix Flow Reactor™与实验设计软件并行使用,可以快速优化S N Ar协议。该协议促进了广泛范围的2-氨基喹唑啉的有效合成,并扩展到2-氨基喹喔啉和2-氨基苯并咪唑。
