  Studies on the synthesis of orthogonally protected azalanthionines, and of routes towards β-methyl azalanthionines, by ring opening of N-activated aziridine-2-carboxylates

  摘要：

  Orthogonally protected azalanthionines were successfully synthesised by the ring-opening of N-activated aziridine-2-carboxylates with protected diaminopropanoic acids (DAPs). The required DAPs were also prepared by ring-opening of N-activated aziridine-2-carboxylates with para-methoxybenzylamine, but it was found that the choice of aziridine protecting groups dictated both the success of the reaction as well as the regioselectivity of the isolated products. Attempts to extend the methodology to the preparation of the more sterically demanding beta-methyl azalanthionines have, so far, been unsuccessful. (C) 2014 Elsevier Ltd. All rights reserved.

  the lantibiotics. We report here a new approach to the synthesis of protected lanthionine, using a novel variant of the Mitsunobu reaction in which catalytic zinc tartrate is used to enhance the nucleophilicity of the thiol. In the course of these studies, we have also demonstrated that the synthesis of lanthionine from trityl-protected beta-iodoalanines is prone to rearrangement, via an aziridine, to

  羊毛硫抗生素的合成方法是硫醚桥连的抗菌肽家族，需要灵活的合成途径来合成多种正交保护的羊毛硫氨酸1衍生物。羊毛硫氨酸的最直接方法涉及半胱氨酸与丙氨酸β-阳离子等效物的反应。对于丙氨酰基β-阳离子等同物存在几种可能性，包括在光延条件下丝氨酸的直接活化：然而，在光延反应中硫亲核试剂的低反应性先前已排除了其在羊毛硫抗生素合成中的用途。我们在这里报告了一种新的合成受保护的羊毛硫氨酸的方法，它使用了Mitsunobu反应的新变体，其中使用酒石酸锌催化作用来增强硫醇的亲核性。在这些研究过程中，
