Cyclic cis-1,3-Diamines Derived from Bicyclic Hydrazines: Synthesis and Applications
Part of the work conducted in our lab and reported in this account has been financed by MESR (ACI 2003), ANR (TrigerRNA), Université Paris Descartes and Satt IDFInnov.
Abstract
Cyclic cis-1,3-diamines are versatile building blocks frequently found in natural molecules or biologically active compounds. In comparison with widely studied 1,2-diamines, and despite their chemical similarity, 1,3-diamines have been investigated less intensively probably because of a lack of general synthetic procedures giving access to these compounds with good levels of chemo-, regio-, and stereocontrol. In this Account we will give a general overview of the biological interest of cyclic cis-1,3-diamines. We will then describe the synthesis and potential applications of these compounds with a particular focus on the work realized in our laboratory.
