Controllable chemoselectivity in the coupling of bromoalkynes with alcohols under visible-light irradiation without additives: Synthesis of propargyl alcohols and α-ketoesters

The chemoselectivity of visible-light-induced coupling reactions of bromoalkynes with alcohols can be controlled by simple changes to the reaction atmosphere (N2 or O2). A N2 atmosphere favours propargyl alcohols via a direct C-C coupling process, whereas an O2 atmosphere results in the generation of α-ketoesters through the oxidative CC/C-O coupling pathway.

Reversible addition and elimination of alcohols by vicinal tetracarbonyl compound

In this Letter, we report reversible addition and elimination of alcohols by acyclic vicinal tetracarbonyl compounds. First, the reversible fixation and release behavior of alcohols by an acyclic vicinal tetracarbonyl compound, 1,4-diphenyl-1,2,3,4-butanetetraone (DPBT) was investigated. On the basis of the results, the addition of alcohol to DPBT was carried out to provide the alcohol adduct of DPBT, which has a hemiacetal structure. Furthermore, we discovered the reaction of DPBT with 2 equi amount of methanol.
