Total synthesis of the tylophora alkaloids rusplinone, 13aα- secoantofine, and antofine using a multicatalytic oxidative aminochlorocarbonylation/Friedel-Crafts reaction

Ambrosini, Lisa M.,Cernak, Tim A.,Lambert, Tristan H.

experimental part, p. 4882 - 4887 (2010/08/06)

A rapid synthetic approach to the tylophora alkaloids antofine and 13aα-secoantofine is presented that makes use of a multicatalytic oxidative aminochlorocarbonylation/Friedel-Crafts reaction as the key step. This reaction, along with a one-pot, three-ste
