1-Alkylamino-l-deoxy-D-fructose

Condensation of 1-alkylamino-l-deoxy-D-fructose (42) with cyclohexane-1,3-diones is a simple reaction that leads to 3-(D-arahmo-tetritol-l-yl)-l,5,6,7-tetrahydroindol-4-ones (45) in high yield [74JCS(P1)1237] (Scheme 13). [Pg.172]

Alkylamino-l-deoxy-D-fructoses (32, R = n-C4H9, CHaCOjCaHs, CHaCeHs) react with the same dicarbonyl compounds giving the corresponding A-alkylpyrroles (33, R = ri-C4H(, (ilHaCOaCsHs, CHaCeHa R = OCaHa, Similarly, 1-arylamino-l-deoxy-D-fructoses (32,... [Pg.312]
