HBF4-Catalysed Nucleophilic Substitutions of Propargylic Alcohols

The activity of HBF4 (aqueous solution) as a catalyst in propargylation reactions is presented. Diverse types of nucleophiles were employed in order to form new C-O, C-N and C-C bonds in technical acetone and in air. Good to excellent yields and good chemoselectivities were obtained using low acid loading (typically 1 mol-%) under simple reaction conditions. The activity of HBF4 (aq. solution) as a catalyst in propargylation reactions is presented. C-O, C-N and C-C bonds were formed in technical acetone and in air. Good to excellent yields were obtained using low acid loading (typically 1 mol-%) under mild reaction conditions.

The coupling-isomerization approach to enimines and the first sequential three-component access to 2-ethoxy pyridines

The coupling-isomerization reaction (CIR) of electron-deficient halides 1 with N-[1-(hetero)arylprop-2-ynyl] tosyl amides 2 leads to the formation of N-tosyl enimines 3, in good to excellent yields. These electron deficient heterodienes are perfectly suit
