Aerobic base-catalyzed rearrangement in triterpenic indoles: an access to spirooxindoles, indolenines, and quinolones
Anastasiya V. Kerimova, Alexander I. Poptsov, Liana M. Zakirova, Tatyana V. Rybalova, Dmitriy N. Polovyanenko, Oxana B. KazakovaA mild, base-catalyzed aerobic rearrangement enables the conversion of readily available indolo-triterpenoids into spirooxyindoles, C2-substituted indolenines, and quinolones. The first example of a triterpenic C1(2)-epoxy-derivative was observed.
