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.
Access to Macrocyclic Lactams. Application to a New Series: the Dibenzotetralactams
Arnaud, Nathalie,Picard, Claude,Cazaux, Louis,Tisnes, Pierre
, p. 5531 - 5534 (2007/10/02)
A facile route is described for the synthesis of macrocyclic dibenzotetralactams derived from 1,2-diaminobenzene based on a stepwise approach using diacid dichlorides or mixed pivalic dianhydrides for ring closure.This method is applicable for the prepara
