Catalytic Enantioselective Diboration of Cyclic Dienes. A Modified Ligand with General Utility
摘要:
The enantioselective 1,4-diboration of cyclic dienes with a new taddol-derived phosphonite ligand occurs with excellent enantioselectivity. Oxidation delivers the derived 1,4-diol, whereas homologation can be used to deliver a chiral 1,6-diol.
