The acid-catalysed reaction of 4,1',6'-trichloro-4,1',6'-trideoxy-galacto- sucrose (1) with 5.5 equiv. of 2-methoxypropene in N,N-dimethylformamide followed by acetylation gave 3',4'-di-O-acetyl-4,1',6'-trichloro-4,1',6'-trideoxy-2,3-O- isopropylidene-6-O-(1-methoxy-1-methylethyl)-galacto-sucrose (2, 2%), 6,3',4'- tri- O-acetyl-4,1',6'-trichloro-4,1',6… CONTINUE READING
