Kauranes, synthesis

In 2014, Canesi s group also reported on a remarkable application of their chemistry that enabled them to develop an asymmetric synthesis of the tetracyclic main core of kaurane diterpenes [131]. The phenolic non-conjugated enyne 249 was elaborated to fulfill the reactivity and stereochemistry requirements of the intended oxidative cationic polycyclization [132], in tandem with apinacolic transposition. After chlorination of the benzylic alcohol of 249 with inversion of configuration, the use of BTI rapidly promoted this dearomative tandem process, which thus... [Pg.62]
