fascinating bioactivity, however, the highly efficient synthesis of this molecule is still an unsolved challenge. Herein, the first asymmetric synthesis of TBAJ-587 based on a synergistic Li/Li bimetallic system is reported. The product could be obtained in an excellent yield of 90% and an enantiomeric ratio (er) of 80:20. Furthermore, the reaction could be conducted on a 5 g scale, and the product
TBAJ-587是抗结核药物贝达
喹啉(BDQ)的类似物,带有二芳基
喹啉骨架,与母体分子相比,保留了较高的细菌效力,毒性较小,并且具有更好的药代动力学特征,已进入I期临床试验。然而,与其令人着迷的
生物活性相比,该分子的高效合成仍然是一个尚未解决的挑战。在此,报道了基于协同Li/Li双
金属体系的TBAJ-587的首次不对称合成。产物收率高达90%,对映体比(er)为80:20。此外,反应可以在5g规模下进行,经过简单的重结晶后得到99.9:0.1er的产物。该方案的实现将极大地满足临床药品生产的需求。
