| titleOfInvention | NEW D-GLUCOSAMINE DERIVATIVES |
| abstract | D-glucosamine derivs. of formula (I) and (II) are new where R is alkenyl, aminoalkyl and R1 is H and acyl D-glucosamine derivs. of formula (III) are also new. Where Ra is H, alkyl, alkenyl, aminoalkyl and R1 is H or acyl. Prodn. of (I) and (II) comprises reacting D-glucosamine derivs. of formula (IV) with L-fucose derivs. of formula (V). In (IV) Rb is alkyl, alkenyl, aryl, R1 is acyl R2 and R3 are bifunctional, alkyl silyl, alkylidene, arylidene, protective gp. and R4 is H or, independently of R3 and R4 a bifunctional protective gp. as above. The reaction is carried out in an inert solvent e.g. ether or (N,N-dimethylformamide using heavy metal salts e.g. silver or mercury salts or thiophillic reagents as catalysts. In (V), Rc is halogen, thioalkyl, trichloracetimidate, R2 is arylmethyl R3 and R4 are alkyl, aryl, acyl, alkylider or arylidene. The prod. is chromatographically purified and the protective gps. removed. |
