  Asymmetric synthesis of homoproline derivatives via Rh(I)-catalyzed hydrogenation using chiral bisphosphines as ligands

  摘要：

  It has been demonstrated for the first time that Rh(I)-catalyzed asymmetric hydrogenation of cyclic beta-enamino acid derivatives I using chiral bisphosphines could be a highly efficient synthetic method for optically active homoproline derivatives. The enantioselectivity and conversion yield were largely dependent upon the chiral ligand. Using the Me-BDPMI forming a seven-membered metal chelate, the N-acetylated beta-enamino acid methyl ester la was hydrogenated to give optically active homoproline derivative 2a with 100% conversion and 96% ee.

  A new method for the preparation of Xxx-Gly (E)-alkene dipeptide isosteres (EADIs), using LDA deprotonation followed by 1 N HCl quench, was explored. The method, named kinetic deconjugation, enabled the synthesis of Tyr-Gly, Gly-Gly, Ser-Gly, Pro-Gly, and Phe-Gly EADIs, as well as one Tyr-Gly trisubstituted alkene dipeptide isostere (TADI). Overall, this method, based on commercially available materials

  探索了一种新的制备Xxx-Gly（E）-烯烃二肽等排物（EADIs）的方法，该方法使用LDA脱质子化，然后用1 N HCl淬灭。该方法称为动力学解偶联，能够合成Tyr-Gly，Gly-Gly，Ser-Gly，Pro-Gly和Phe-Gly EADIs，以及一种Tyr-Gly三取代烯烃二肽等排物（TADI）。总体而言，该方法基于可商购的材料，可实现高收率，仅需很少的合成步骤，并且可以在多种EADI的合成中达到克级。
