Xanthenedione derivatives were prepared through lnCl3·4H2O promoted condensation of aldehydes with 5, 5-dimethyl-1, 3-cyclohexandione in [bmiml[BF4]. The advan
Photochemical [2+2] cycloaddition of C60 with podophyllotoxin derivative containing a cyclohexadienone group in o-dichlorobenzene afforded an isomeric mixture o
