  Heteroatom-directed metalation. Lithiation of N-propenylbenzamides and N-propenyl-o-toluamides. Novel routes to ortho-substituted primary benzamide derivatives and N-unsubstituted isoquinolin-1(2H)-ones

  摘要：

  Reaction of N-propenylbenzamides 4 and 9, obtained by LDA-induced isomerization of the corresponding N-allylbenzamides 1, 8, and 14, with 2 equiv of sec-butyllithium or tert-butyllithium at low temperature regiospecifically generates the highly reactive N,ortho-dilithiated species (e.g., 5 and 17). These dilithio species react avidly with a wide spectrum of electrophilic reagents, including alkyl halides, giving adducts which on hydrolysis with warm 50% aqueous acetic acid are converted into ortho-substituted primary benzamides in excellent yields. Ortho-lithiation of N-propenylbenzamides is thus formally equivalent to ortho-lithiation of primary benzamides themselves. The utility of this important, previously unknown, synthetic operation is enhanced by the well-known facility with which the primary amide moiety can be transformed into other useful functional groups, as exemplified by the synthesis of 2-methoxy-6-methylbenzoic acid (12) and 2-methoxy-6-methylbenzonitrile (13) from N-propenyl-2-methoxybenzamide (9), N-Propenyl-o-toluamide (7) undergoes regiospecific dilithiation on nitrogen and on the methyl group under conditions analogous to those used for the N-propenylbenzamides. These dilithio species react with DMF or "Weinreb type" amides to give condensation products which cyclize to N-propenylisoquinolin-1(2H)-ones under midly acidic conditions. Removal of the N-propenyl moiety under more strongly acidic conditions provides N-unsubstituted isoquinolin-1(2H)-ones with high overall efficiency. This process is exemplified by the synthesis of isoquinolin-1(2H)-one (23) and its 3-n-butyl congener 26 from N-propenyl-2-methylbenzamide (7).

  2-Dimethylaminomethylidene-1,3-diketones are useful synthons for the construction of 5-acyl-6-substituted-3-cyano-2(1H)-pyridinones. The reaction of these 1,3-diketones and the anion of cyanoacetamide gave the title compounds. When the 1,3 diketone contained different alkyl or aryl groups, mixtures of regioisomers were formed. To circumvent this problem, dimethylaminomethylidene hydrazones, regioselectively

  Pseudomonas aeruginosa (P. aeruginosa) is an opportunistic human pathogen that forms biofilms and produces virulence factors via quorum sensing (QS). Blocking the QS system in P. aeruginosa is an excellent strategy to reduce biofilm formation and the production of virulence factors. RhlR plays an essential role in the QS system of P. aeruginosa. We synthesized 55 analogues based on the chemical structure

  铜绿假单胞菌（P.aeruginosa）是一种机会性人类病原体，可形成生物膜并通过群体感应（QS）产生毒力因子。阻断铜绿假单胞菌的QS系统是减少生物膜形成和产生毒力因子的极好策略。RhlR在铜绿假单胞菌的QS系统中发挥重要作用。我们基于4-gingerol的化学结构合成了55个类似物，并使用基于细胞的报告基因菌株测定法评估了它们的RhlR抑制活性。全面的结构-活性关系研究确定了炔基酮30作为最有效的RhlR拮抗剂。该化合物对LasR和PqsR表现出选择性的RhlR拮抗作用，对生物膜的形成有很强的抑制作用，并减少了铜绿假单胞菌中毒力因子的产生。此外，用30只体内处理的黄粉虫幼虫的存活率大大提高。因此，化合物30，一种纯的RhlR拮抗剂，可以用于开发铜绿假单胞菌感染的QS调节分子。
