Abstract

Synthetic Studies on (+)-Hydantocidin.Part 3. A New Synthetic Method for Construction of the Spiro-Hydantoin Ring at the Anomeric Position of D-Ribofuranose.-A facile route for the large-scale preparation of hydantocidin (IX) starts from the protected D-psicose (I) which, in turn, is prepared from D-fructose with 39% yield. -(MIO, S.; KUMAGAWA, Y.; SUGAI, S.; Tetrahedron 47 (1991) 12-13, 2133-2144; Agric.
