摘要:Abstract(#br)The domino reactions of alkyne-tethered N-mesylhydrazones yielding fused polycyclic pyrazoles have been studied within the Molecular Electron Density Theory (MEDT). Analysis of the Gibbs free energies indicates that the more favourable reactive path is the one in whi...

摘要:Abstract(#br)The domino reactions between enaminones and sulfonyl hydrazines enabling novel synthesis of pyrazoline have been achieved by employing water as reaction medium and acetic acid as cheap and green additive are reported. Two new C N and one new C N bonds have been const...

摘要:Abstract(#br)A new combinatorial method for the preparation of substituted thiazolo[4,5- b ]pyridines, which utilizes cyanoacetamide, heterocumulenes (isothiocyanates, carbon bisulfide), and ethyl-4-chloroacetoacetate in a new S N 2→Thorpe–Ziegler→Thorpe–Guareschi domino reactions...

摘要:... In these domino reactions, we can control the reaction conditions to give three new products: pyrano[2,3- b ]indol, dihydropyrano[2,3- b ]indol with E or Z exocyclic double bond. Using DABCO as catalyst in THF, dihydropyrano[2,3- b ]indol with E exocyclic double bond and py...
