MnBr2 catalyzed regiospecific oxidative Mizoroki-Heck type reaction

Herein, we report an unprecedented regiospecific oxidative Mizoroki-Heck type reaction for the synthesis of ɑ-difluoromethyl homoallylic alcohols. The reaction shows broad substrate scopes and high functional group tolerance. Late-stage functionalization of complex biologically active molecules demonstrates the synthetic potential of this transformation. Mechanistic study supports the involvement of MnBr2 catalyzed radical 1,2-silyl transfer.

Nickel-Catalyzed Reductive Allylation of Tertiary Alkyl Halides with Allylic Carbonates

The construction of all C(sp3) quaternary centers has been successfully achieved under Ni-catalyzed cross-electrophile coupling of allylic carbonates with unactivated tertiary alkyl halides. For allylic carbonates bearing C1 or C3 substituents, the reaction affords excellent regioselectivity through the addition of alkyl groups to the unsubstituted allylic carbon terminus. The allylic alkylation method also exhibits excellent functional-group compatibility, and delivers the products with high E selectivity.

A synthesis of allylboronates via the palladium(0)-catalyzed cross-coupling reaction of bis(pinacolato)diboron with allylic acetates

The cross-coupling reaction of bis(pinacolato)diboron [(Me4C2O2)BB(O2C2Me4)] with allyl acetates regio- and E-stereoselectively provided the pinacol esters of allylboronic acids in high yields. The reaction was efficiently catalyzed by Pd[dba]2 in DMSO at 50°C.
