Diastereoselective Ring Homologation of Bicyclic Hydrazines: Access to cis -1,3-Diaminocyclohexitols
Résumé
A sequence of oxidative cleavage/double nitroaldol condensation followed by a few simple synthetic transformations can lead to polyhydroxylated di-and triaminocyclohexanes from a readily available bicyclic hydrazine. This new synthetic route provides a simple and general access to densely substituted privileged scaffolds or fragments with a perfect control of their relative configuration.
