The reactivity of 4-(1-butoxyvinyl)-2H-chromen-2-one (1) and (E)-4-(2-butoxyvinyl)-2H-chromen-2-one (2) as diene in thermal Diels-Alder cycloaddition reactions with several electron-poor dienophiles is reported. Among several dienophiles used in this stud

An efficient synthesis of a series of methyl ketones at the C4 position of coumarins, coumarin-containing heterocycles and analogous scaffolds is reported via very high α-regioselective Heck coupling using tosylates and in very high yields. Although α-reg

(Chemical Equation Presented) Highly regioselective Heck couplings of α,β-unsaturated tosylate and mesylate derivatives with N-acyl N-vinylamines and vinyl ethers were achieved. Several 2-alkoxy-1,3-dienes and 2-acylamino-1,3-butadienes were synthesized i
