A method for the synthesis of allylboronates via Zweifel-type deprotonative olefination was demonstrated. Tetrasubstituted vinylboronates were used as the substrates. NCS (N-chlorosuccinimide) was used as a bifunctional additive, electrophile and base. This method exhibited a different elimination strategy in Zweifel type transformation to afford allylboronates. The homo-alcohols and alkenes were stereoselective synthesized from the obtained allylboronates, demonstrating the synthetic value of this methodology. (Figure presented.).
A one-pot cross-pinacol coupling/rearrangement procedure
Scheffler, Ulf,Mahrwald, Rainer
, p. 1970 - 1975,6 (2012/12/12)
A new catalytic retro-pinacol/cross-pinacol reaction, followed by subsequent rearrangement or deoxygenation of the intermediately formed vicinal diols, is described. This operationally simple one-pot protocol allows isolation of geminal α,α-diphenyl ketones or 1,1-diphenyl alkenes with high yields and selectivities. Copyright
Sp3-sp2 C-C bond formation via Bronsted acid trifluoromethanesulfonic acid-catalyzed direct coupling reaction of alcohols and alkenes

A novel and efficient trifluoromethanesulfonic acid-catalyzed sp 3-sp2 Ci￡C bond formation reaction through the direct coupling of alcohols with alkenes has been realized under mild conditions. The present protocol provides an attractive approach to a diverse range of polysubstituted olefins in good to excellent yields with high stereo- and regioselectivities. Copyright
