4-substituted pyridine or a 1-substituted imidazole ring and the carboxamide nitrogen atom showed the best combination of potencies in the two assays. Several of these compounds were found to be orallyactive inhibitors of LTE4-induced bronchoconstriction in the guinea pig and LTE4-induced skin wheal formation in the rat. One of the most potent analogues, 2-(1-methyl-ethyl)-N-(1H-imidazol-1-ylbutyl)-11-oxo-11H-pyrido
Synthesis of β-heteroaryl carbonyl compounds via direct cross-coupling of allyl alcohols with heteroaryl boronic acids under cooperative bimetallic catalysis
The eco-friendly cooperative Cu/Pd-catalyzed oxidative Heck reaction of allyl alcohols with heteroaryl boronic acidsunder air was described. The ready availability of starting materials and the mild reaction conditions made this protocol a safe and operationally convenient strategy for the efficient synthesis of β-heteroaryl carbonyl compounds.
