SYNTHESIS OF HEXACYCLIC INDOLE ALKALOIDS RELATED TO VINDOLININE BY SONOCHEMICAL CYCLIZATION
Hugel, Georgette,Cartier, Dominique,Levy, Jean
, p. 4513 - 4516 (2007/10/02)
Upon treatment with sodium in THF under sonication, 19-iodotabersonine underwent cyclization to the vindolinine ring system.The yields and ratio of the diastereomers thus obtained depended on the sonication parameters.
