Abstract

NEW MATERIAL:The compound of formulaI(R1 and R2 are H or acetyl; R3 is H or benzyl; R4 is H, benzyl or halogen; m is 0W2; n is 0W4; m+n is 2W6).
USE: Intermediate for the synthesis of mannan useful as an antitumor agent.
PROCESS: For example, the compound of formula II is converted to the compound of formula III by deacetylation followed by benzylation. the compound of formala III is heated in the presence of a catalyst, and then deacetylated to obtain the compound of formula IV (Bn is benzyl), which is made to react with the compound of formula V (X is halogen) and subjected to the deacetylation and debenzylation to afford the compound of formula VI (R1=R2=H).
