Abstract: | Two myo-inositol derivatives (4) and (5), required for the total synthesis of surugatoxin, prosurugatoxin, and neosurugatoxin, were prepared. Synthesis of (+/-)-2,3-O-cyclohexylidene-4,5-O-isopropylidene-1-O-methoxymethyl-myo-i nositol (4) was achieved from (+/-)-1-O-benzoyl-2,3-O-cyclohexylidene-4,5-O-isopropylidene-myo-inosito l (6) in 4 steps, and (-)-2,3-O-cyclohexylidene-1,4-di-O-methoxymethyl-5-O-2',3',4'-tri-O-ace tyl- beta-D-xylopyranosyl]-myo-inositol (5) was synthesized from (+/-)-1-O-benzoyl-2,3-O-cyclohexylidene-5,6-O-isopropylidene-myo-inosito l (12) in 7 steps. |
