Patent number: 4623721Abstract: It is disclosed that L-fructose can be produced in high yield from L-sorbose. The process involves the inversion of the hydroxyl groups on carbon atoms C3 and C4 of L-sorbose to produce L-fructose. This inversion can be accomplished in simple, commercial equipment with the aid of common reagents. L-sorbose or an appropriately blocked derivative thereof is reacted so as to introduce or create a good leaving group, preferably mesyl or tosyl, at chiral carbon C3 thereby displacing the hydroxyl previously at that position. The leaving group is then displaced, preferably under alkaline conditions, in such a way that the hydroxyl oxygen atom at chiral carbon C4 attaches to chiral carbon C3, thereby displacing the leaving group while forming a 3,4-oxirane (epoxide) ring. The 3,4-oxirane ring forms in a downward position relative to the Haworth presentation thereby inverting chiral carbon C3 during formation of the 3,4-oxirane ring.Type: GrantFiled: May 23, 1984Date of Patent: November 18, 1986Assignee: Purdue Research FoundationInventors: Chyi-Cheng Chen, Roy L. Whistler

Patent number: 4420489Abstract: Simple sugars with sulfur replacing the ring oxygen atom protect normal healthy cells of animals from radiation or from any other reaction that produces free radicals and damages the cells through the action of the free radicals. To be effective, the thio-sugars must undergo transport to cells that may be adversely affected by free radicals. 6-Thio-D-fructose is an example of a sugar that is readily transported from the gastrointestinal tract to the cardiovascular system and thereby disseminated to cells throughout the body. As it is absorbed into the cells, it protects against all kinds of radiation that adversely affects cells through the creation of free radicals. It is believed to be effective against all high-energy radiation that produces free radicals in living material, and therefore is effective against radiation such as X-ray, gamma, alpha, pi mesons, neutrons, and ultraviolet light radiation. Therefore, it even offers protection against sunburn.Type: GrantFiled: October 7, 1981Date of Patent: December 13, 1983Assignee: Purdue Research FoundationInventor: Roy L. Whistler

Patent number: 4413120Abstract: A process for synthesizing acosamine, daunosamine and 1-thioacosamines from L-rhamnal is disclosed that can generally be characterized by Michael addition of an alkoxide or thioalkoxide to the enone formed by allylic oxidation of L-rhamnal to directly generate the 2-deoxy functionality, and stereospecific reduction of the oxime to the arabino compound which establishes configuration at C-3 and generates a compound which requires only epirmerization at C-4 to yield the desired product. The synthesis of anthracycline antibiotics incorporating these sugars or their derivatives by glycosidation of the glycone is also disclosed.Type: GrantFiled: April 6, 1981Date of Patent: November 1, 1983Assignee: Purdue Research FoundationInventor: Roy L.
