• Kinetic deconjugation: a gateway to the synthesis of Xxx-Gly (E)-alkene dipeptide isosteres

  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。

  The reactions of protected serine- and threonine-derived gamma-(mesyloxy) alpha,beta-unsaturated esters with various magnesio organocyanocopper Lewis acid complexes have been investigated. The formation of syn-S(N)2' products, in addition to the normally expected anti-S(N)2' products, is taken as an indication that the reaction proceeds by a mechanism involving coordination of the magnesiocuprate with the C(delta)-N:C(gamma)-O syn-gamma-(mesyloxy) alpha,beta-enoates.

  A stereoselective synthesis of protected (E)-alkene dipeptide isosteres by the reaction of the mesylates of homochiral delta-aminated gamma-hydroxy (E)-alpha,beta-enoates with either RCu(CN)Li.BF3 or RCu(CN)MgX.BF3 reagent is described. The degree of diastereoselectivity has been found to be uniformly high except for the serine- and threonine-derived acetonides 77 and 81. The synthesis permits the introduction of sterically hindered appendages such as isopropyl and tert-butyl groups at the alpha position to the ester group. This methodology provides a new route to a wide range of modified (E)-alkene peptide mimics that may have biological importance.
