Abstract Reaction of 2-functional alkyl-1,3-diketones with 30% aqueous formaldehyde using aqueous 6-10M potassium carbonate solution as base, afforded a-functional alkylvinylketones in good yields.
Astacin metalloproteinases, in particular meprinsα and β, as well as ovastacin, are emerging drug targets. Drug‐discovery efforts have led to the development of the first potent and selective inhibitors in the last few years. However, the most recent compounds are based on a highly flexible tertiary amine scaffold that could cause metabolic liabilities or decreased potency due to the entropic penalty
