A highly convergent synthesis of the phytoalexin elicitor hexasaccharide

A highly convergent synthesis of the elicitor-active D-glucohexatose 1 and its variant 19 was achieved via coupling of the trisaccharide donor 14 with the trisaccharide acceptor 15 followed by deprotection. 14 and 15 were obtained from rearrangement of the orthoesters 6 and 5 respectively which were...

Description
Summary:A highly convergent synthesis of the elicitor-active D-glucohexatose 1 and its variant 19 was achieved via coupling of the trisaccharide donor 14 with the trisaccharide acceptor 15 followed by deprotection. 14 and 15 were obtained from rearrangement of the orthoesters 6 and 5 respectively which were prepared quantitatively from coupling of the disaccharide 4 with acetobromoglucose and 6-O-chloroacetylated acetobromoglucose respectively.
