New synthesis of vaulted biaryl ligands via the Snieckus phenol synthesis.
Org. Lett. 7 , 367, (2005) [reaction: see text] In an effort to develop a synthesis of the VAPOL ligand that avoids the use of a chromium carbene complex, a route was examined that involved the annulation of a naphthalene carboxamide via the method of Snieckus. The latter derivatives c... |

Highly enantioselective deracemization of linear and vaulted biaryl ligands.
Org. Lett. 5 , 1813, (2003) [reaction: see text] A copper-mediated deracemization of the vaulted biaryl ligands VANOL and VAPOL can be readily achieved in the presence of (-)-spartiene. The optimal procedure involves the in situ generation of copper(II) and leads to the reproducible for... |
