Research Abstract |
Total synthesis of (+)-dienomycine which is piperidine alkaloid, synthesis of tetrahydropyran frame of yessotoxin, novel synthesis of sugars such as D-ribose, D-deoxyriboe, and spiroC-arylglycoposide derivatives, and the spiroketal ring which is the basic skeleton of spirofungins through the Pd catalyzed cyclization were done well. Stereo-selective construction of the conjugate dienes which are parts of spirofungins also were developed.
