Action of alkali on O-benzylated aldoses: a simple rationalization of some reactions occurring in alkaline media
摘要:
Treatment of some O-benzyl-protected aldopyranoses and aldofuranoses with sodium 2-propoxide or K2CO3 brought about their equilibration and the loss of the elements of benzyl alcohol, with concomitant formation of a Z aldehyde. The latter rearranged rapidly in solution to the corresponding E lactol.
Boron enolates in stereoselective syntheses of 2-enitols from O-benzyl aldoses by reaction with borohydride in 2-propanol. Configuration of E and Z enols from proton relaxation rates
