Efficient Asymmetric Syntheses of 1‑Phenyl-phosphindane, Derivatives, and 2- or 3‑Oxa Analogues: Mission Accomplished
2014-05-16T00:00:00Z (GMT) by
A highly enantioselective synthesis of unsubstituted 1-phenyl-phosphindane and its <i>P</i>-borane and <i>P</i>-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-<i>P</i>-borane analogue was otherwise achieved via a tandem <i>P</i>-α-iodination–intra-<i>O</i>-alkylation.
