The effective conversion of RA-VII 1 into the naturally less-accessible RA-II 4 has been devised through boron tribromide bis-O-demethylation and successive selective partial O-methylation using diazo(trimethylsilyl)methane. The O-triflate 11 prepared from RA-II 4 was subjected to cross-coupling reaction with alkylstannanes to produce analogues 12, 13 and 15, while compounds 13 and 15 were later converted into analogues 14 and 16, respectively. Analogues 12-16 showed antitumour activity against P-388 leukaemia both in vitro and in vivo.
