The current application relates to a pharmaceutical composition for the treatment or amelioration of a neurological disease, wherein the composition comprises a therapeutically effective amount of a caspase-6 inhibitor which is an arylpropynamide derivative. The composition can be formulated for oral or topical administration, subcutaneous, intravenous, or intramuscular injection, infusion, inhalation, or intrthecal injection.
annulation of 2-iodo enol esters leading to 4- and 3,4-substituted isocoumarins was accomplished selectively at room temperature. Coupling of 2-iodo benzoic acids with enolates that were produced in situ from the simple esters was also performed to produce isocoumarins under analogous reaction conditions. Owing to the mildness of the current protocol, 4-acyl 3-substitutedisocoumarins were efficiently produced
An organobase-catalyzed 1,1-diborylation of terminal alkynes from propargylic derivatives with bis(2,4-dimethylpentane-2,4-glycolato)diboron (B2oct2) is first reported, regioselectively providing 1,1-diborylalkene products with high efficiency. The catalytic pathway is well postulated on the basis of DFT calculations.

Copper-catalyzed stereo- and regioselective hydrophosphorylation of terminal alkynes: scope and mechanistic study
highly stereo- and regioselective hydrophosphorylation of terminalalkynes to E-alkenylphosphorus compounds was well developed. It represents a general and practical hydrophosphorylation method, of which diarylphosphine oxide, dialkylphosphine oxide and dialkyl phosphite all had effective P(O)H parts to react with different types of terminalalkynes. Contrary to previous air-sensitive reports, all the reactions
