Benzenesulfonamide derivatives of 2-substituted 4H-3,1-benzoxazin-4-ones and benzthiazin-4-ones as inhibitors of complement C1r protease
摘要:
A series of 2-sulfonyl-4H-3,1 -benzoxazinones was prepared that inhibit Clr protease in vitro. Several compounds were found to be selective for Clr verses the related serine protease trypsin. Selected compounds demonstrated functional activity in a hemolysis assay. (C) 1999 Elsevier Science Ltd. All rights reserved.

Pd and CO—ureally got me! The title reaction proceeds efficiently at 18 °C under CO (1 atm) with 5 % [Pd(OTs)2(MeCN)2] as precatalyst. Depending on the solvents used, either anthranilates or cyclic imides can be obtained in high yields (see picture, BQ=benzoquinone, Ts=4‐toluenesulfonyl).
Pd 和 CO - 真的抓住了我!标题反应在 18 °C 下在 CO (1 atm) 下有效进行,使用 5% [Pd(OTs) 2 (MeCN) 2 ] 作为预催化剂。根据所使用的溶剂,可以高产率获得邻氨基苯甲酸酯或环状酰亚胺(见图,BQ=苯醌,Ts=4-甲苯磺酰基)。

Two-stage reaction of methyl anthranilate with aryl(alkyl) isocyanates in keeping with the quantum-chemical calculations and XRD analysis resulted in 3-aryl(alkyl) quinazoline-2,4(1H,3H)-diones that by treatment with alkyl halides, phenacyl bromides, esters and amides of chloroacetic acid were converted into the corresponding 1-alkyl derivatives.
