The reactions of arylamine with ethyl acetoacetate catalyzed by a solid support are accelerated by microwave irradiation to result in a rapid and clean producti
Microwave-assisted allylic oxidation at C-13 position of 14-deoxysinenxan A wasdescribed. This new method (150℃/10 mir/5 bar on microwave synthesizer) led to a
A facile synthetic route to two seco-eudesmane, 4, 5-dioxo-10-epi-4, 5-seco-γeudesmane (1) and 4, 5-dioxo-10-epi-4, 5-seco-γ-eudesmol (2) from (+)-dihydrocarv
β-Keto-δ-valerolactones, which were obtained by reaction of acetoacetate with aldehydes or ketones, reacted with carbon disulfide, alkyl halides and a new con
4-Amino-5-(pyridin-3-yl)-4H-1,2,4-triazole-3-thiol 1 were condensed with 2-bromo-1-(substituted phenyl)ethanone to give pyridinyltriazolothiadiazines 2a~c, which
