- Abstract:
-
Regioselective complexation of the dimethoxy arene ring of canadine to the Cr(CO)2 moiety gives two diastereoisomers which are separated by flash chromatography. Deprotonatlon of either diastereoisomer with n-butyllithium followed by addition of methyl iodide or trimethylsilyl chloride gives C11-methyl- or -trimethylsilylcanadine after decomplexatlon. Each diastereoisomer of the C11-trimethylsilylcanadine complex may be treated with base and methyl iodide to give, after desilylation and decom...
