The fused triazole derivatives,which is an important inhibitors of the dipeptidyl peptidase-Ⅳ enzyme(DPP-Ⅳ),can be used for the treatment or prevention of type 2 diabetes.A new fused triazole derivatives of 3-oxo-3-...The fused triazole derivatives,which is an important inhibitors of the dipeptidyl peptidase-Ⅳ enzyme(DPP-Ⅳ),can be used for the treatment or prevention of type 2 diabetes.A new fused triazole derivatives of 3-oxo-3-[3-trifluoromethyl-5,6-dihydro[1,2,4]-triazolo[4,3-a]pyrazin-7(8H)-yl]-1-phenylpropan-1-amine was synthesized from 2-chloropyrazine and benzaldehyde by hydrazinolysis,trifluoroacetylation,cyclization,hydrogenation,condensation and deprotection reaction.The structures of the compound and its intermediates were determined by IR,NMR,and MS.展开更多
1,2-Bis(4-hydroxy-3-methoxyphenyl)ethane,a by-product formed from synthesis reaction of vanillyl nonanoate,is separated by silica-gel column chromatography and characterized by 1HNMR,13CNMR and MS.
