Abstract
A process for producing a compound represented by the following formula (2): (2) (wherein R1 means hydrogen, methyl, or CH2OH; R2 means hydrogen or methyl; R3 means hydrogen or hydroxy; R4 means hydrogen or hydroxy; and R5 means hydroxy, a sugar chain, or a protective group) or a salt of the compound. The process comprises subjecting a compound represented by the following formula (1): (1) (wherein R1 to R5 have the same meanings as the R1 to R5 in the formula (2)) to a cyclization metathesis reaction in the presence of a catalyst.
