  Spirodienone and Bis(spirodienone) Derivatives of Calix[4]naphthalenes

  摘要：

  Calix[4]naphthalenes 11 and 12 in which hydroxyl groups are situated intraannularly can be oxidized with PTMATB and base to form the bis(spirodienone) 13, from 11, and bis(spirodienone) 20-21 and spirodienone 22, from 12. The prototype calix[4]naphthalenes 9 and 10 previously reported by us and which contain similar 1,5 dihydroxy functionalities extrannularly failed to afford the analogous spironaphthalenones. Model studies with the bis(1-hydroxy-2-naphthyl)methanes 8-8f provided support for the putative mechanism proposed for the formation of spirodienone calix[4]arenes and spironaphthalenones. The synthesis of the novel tert-butylcalix[4]naphthalenes 12 is described.

  resolved chiral ligands. In this Letter, we optimize the asymmetric addition of diethylzinc to aldehydes by modification of achiral methylene bis(phenol) ligands. Upon coordination of the substrate, the achiral ligand becomes asymmetric, a concept termed Metal Geometry-Induced Ligand Asymmetry. The enantioselectivity of the catalyst formed from a single resolved ligand and several achiral ligands ranged from
