• Design and Synthesis of Benzosultine-sulfone as a <i>o</i>-Xylylene Precursor via Cross-enyne Metathesis and Rongalite: Further Expansion to Polycyclics via Regioselective Diels−Alder Reaction
  作者：Sambasivarao Kotha、Arjun S. Chavan

  DOI：10.1021/jo100655c

  日期：2010.6.18

  Benzosultine-sulfone 5 has been prepared as a o-xylylene or o-quinodimethane precursor by utilization of rongalite. Thermal activation of this hybrid molecule 5 has resulted a new sulfone-based building block 6. Building block 5 is a suitable precursor for the synthesis of unsymmetrically functionalized polycyclics through Diels-Alder (DA) chemistry. The dibromosulfone 24 and benzosultine-sulfone 5 has also been used for the synthesis of various sulfone based unnatural a-amino acid (AAA) derivatives.
