Thioglycoluril compound, and method for producing same
A novel monothioglycoluril compound and a novel dithioglycoluril compound. A thioglycoluril compound of the following Formula (1): (wherein X is an oxygen atom or a sulfur atom, and four Rs are each a hydrogen atom, a linear, branched, or cyclic alkyl group having a carbon atom number of 1 to 4, a phenyl group, a naphthyl group, a benzyl group, or a C3-9 alkyl group having at least one ether bond on the main chain).
1. A method for producing a monothioglycoluril compound, the method comprising a first step of causing a reaction between formaldehyde and a compound of the following Formula (4a) in a basic aqueous solution, and then isolating a compound of the following Formula (2a); and a second step of causing a reaction between the compound of the following Formula (2a) and an alcohol of the following Formula (5) in an acidic solution containing the alcohol as a solvent, adding a basic aqueous solution to the resultant reaction mixture, and purifying the resultant product by silica gel column chromatography for removal of impurities from the product, so as to produce a monothioglycoluril compound of the following Formula (2b):
(wherein four R 1 s are each a linear, branched, or cyclic alkyl group having a carbon atom number of 1 to 4, a phenyl group, a naphthyl group, a benzyl group, or a C 3-9 alkyl group having at least one ether bond on the main chain).
