• Total Synthesis of Dihydrocodeine and Hydrocodone via a Double Claisen Rearrangement and C-10/C-11 Closure Strategy
  作者：Tomas Hudlicky、Vimal Varghese

  DOI：10.1055/s-0032-1318114

  日期：——

  Dihydrocodeine and hydrocodone were synthesized from bromobenzene in 16 and 17 transformations, respectively. The key steps involved the toluene dioxygenase-mediated dihydroxylation of bromobenzene by whole-cell fermentation with E. coli JM109(pDTG601A), Kazmaier-Claisen rearrangement of glycinate ester, Claisen rearrangement to set the C-13 quaternary center, and C-10-C-11 closure. Experimental procedures are provided for the key steps.
