Studies on the synthesis of the C-glycosidic part of nogalamycin, part 3
Krohn, Karsten,Terstiege, Ina,Floerke, Ulrich
, p. 197 - 215 (2007/10/03)
The addition of the metalated 1,4-dimethoxybenzenes 17a-c to the methyl ketone 14 was investigated in connection with the construction of the C-glycosidic part of nogalamycin. In most reactions, a selectivity towards the undesired (S)-isomer 16a was obser
