Rh(II)-mediated domino [4 + 1]-annulation of α-cyanothioacetamides using diazoesters: A new entry for the synthesis of multisubstituted thiophenes

Autor: Jury J. Medvedev, Ilya V. Efimov, Yuri M. Shafran, Vitaliy V. Suslonov, Vasiliy A. Bakulev, Valerij A. Nikolaev

Publikováno v: Beilstein Journal of Organic Chemistry, Vol 13, Iss 1, Pp 2569-2576 (2017)

A new approach towards the synthesis of multisubstituted thiophenes is elaborated based on Rh(II)-catalyzed domino reactions of acyclic diazoesters with α-cyanothioacetamides. It provides a way for the preparation of 5-amino-3-(alkoxycarbonylamino)t
