✦ Synopsis

The reaction of dimers of phosphole oxides (3a-e) with an excess of dimethylsulfide borane follows an unexpected route to give phosphine-boranes 5a-e based on the 7-phosphanorbornene framework in a regioselective manner and in good yields. In small quantities, the diboranes (10a-e), that can be synthesized in acceptable yields by the reaction of the corresponding diphosphines 12a-e with borane, were also formed.

A new strategy for the convergent assembly of six-membered polycyclic ether ring fragments has been developed based upon the novel reaction between vinylstannanes with tri¯ates in the presence of a strong base. The application of the present method has allowed for a synthetic study of the EFGH ring
