Desymmetrization reactions: A convenient synthesis of aromatic diamide diamines
Picard,Arnaud,Tisnès
, p. 1471 - 1478 (2007/10/03)
A two-step process for the synthesis of various diamide diamines derived from 1,n-diamino benzene compounds is described. The amidation reaction is simple, mild, involves readily available bis(N-acylthiazolidine-2-thione) derivatives as acylating agents and requires only stoichiometric equivalents of diamine and acylating agents.
Macrocyclic polyether tetralactams I: Synthesis and cyclization studies
Duriez,Pigot,Picard,Cazaux,Tisnes
, p. 4347 - 4358 (2007/10/02)
A three-step method for the synthesis of new 18,21 or 24-membered macrocyclic tetralactams with two dimethyleneoxy moieties is described. The method consists in the ring closure of a bis-secondary amine with a diamide diacid derivative activated by the th
