METHOD FOR PRODUCING ATRACTYLODIN AND COBALT COMPLEX COMPOUND
-
Paragraph 0038, (2017/02/24)
PROBLEM TO BE SOLVED: To provide a method for producing atractylodin using a cobalt complex compound of atractylodin where the storage of atractylodin having an unstable chemical structure is made possible for a long period, and the cobalt complex compound. SOLUTION: Provided is a cobalt complex compound represented by formula (I). Also provided is a method for producing atractylodin provided with a step where the cobalt complex compound and a deprotection agent are reacted (A respectively independently denotes CO, P(RA)3 or NO; RA denotes a 1 to 4C straight chain or branched chain alkyl group, phenyl group, aldehyde group, carboxyl group or ester group substituted or unsubstituted with a hydroxyl group, an aldehyde group, a carboxyl group or an ester group; in the case the RA is 2 or more, respectively, independent;and R1 denotes H, a methyl group, a hydroxymethyl group, an aldehyde group or a carboxyl group).

A straightforward synthesis of a series of naturally occurring polyacetylenes has been developed, including the montiporynes A and C, possessing cytotoxic activity against several human solid tumor cells, the atractylodin, with antibiotic activity against Escherichia coli, and triynes, which display insecticidal activities, starting from the readily available 1,4-bis(trimethylsilyl)-1,3-butadiyne.
