The direct allylic C(sp3)–H functionalization provides a straightforward protocol for the synthesis of valuable molecules. We report herein the first chemo- and site-selective method for allylic C(sp3)–H isothiocyanation of various internal alkenes under mild electrochemical conditions. This method exhibits broad functional group tolerance and excellent selectivity and can be applied for late-stage

An In(III)-catalyzed vinylogous addition of O-silyl vinylketene acetals to 2,3-dihydro-4-pyridinones has been developed. The method features the unprecedented employment of supersilyl groups to influence the gamma versus alpha regiochemical control of vinylogous Mukaiyama Michael (vM-Michael) reactions when gamma-substituted O-silyl vinylketene acetals are used. We also demonstrate that these reactions allow facile access to quinolizidine-based alkaloids such as deoxynupharidine and well as lasubine I and II.
