Efficient Asymmetric Syntheses of 1-Phenyl-phosphindane, Derivatives, and 2- or 3-Oxa Analogues: Mission Accomplished

This is the authors' abstract. We don't add key points for this paper.

A highly enantioselective synthesis of unsubstituted 1-phenyl-phosphindane and its P-borane and P-oxide derivatives was effectively established via a new fluoride-triggered desilylative carbocyclization strategy. Preparation of the "oxygen atom-doped" 1-phenyl-3-oxa-1-phosphindane-P-borane analogue was otherwise achieved via a tandem P-α-iodination-intra-O-alkylation.
