Recently,many reports show that the 6-arylpurine derivatives possess anti-HCV,cytostatic,and antimycobacterial activities.Up to now,several methodologies were described for the preparation of 6-arylpu
2-substituted purine nucleosides have received considerable attention due to their broad spectrum of biological activities.Thus,numerous economically important pharmaceuticals,such as cladribine,Regad
1,4-Dihydro-2H-3,1-benzoxazin-2-one is an important structural motif and is widely found in biologically active compounds.For example,efavirenz is a well-known nonnucleoside reverse transcriptase inhi
A transition metal free oxidative dehydrogenative coupling reaction has been developed for the direct construction of novel C60-fused tetrahydrocarbazoles,dibenzothiophenes,benzothiophenes and dibenzo
An efficient redox neutral N-heteroannulation reaction has been developed to selective access unexpected unsymmetrical fulleropyrrolidines and diverse disubstituted 1-fulleropyrrolines using a very si
A facile and direct synthetic method for the synthesis of vicinal tricarbonyl amides(VTAs)in moderate to excellent yields(62-93%)has been developed starting from readily available β-ketoamide in the p
Acridione is a ubiquitious structural motif that exists in a wide range of biologically active compouds.To date,various reactions have been intenstigated leading to the construction.
