First, the carbon-carbon (C-C) bond-forming reaction of aldehydes with bicyclo[m.n.0]-1-oxonium ylides was studied as the ylide was transiently formed in the Rh(II)-catalyzed reaction of a nonenolizable diazoketone, namely, 2-(3-diazo-1,1-dimethyl-2-oxopropyl)-2-methyldioxolane (1). The reaction of 1 with benzaldehyde in the presence of ClTi(Oi-Pr)3 gave… CONTINUE READING
