<CHEM>
wherein, R1 is aryl or heterocyclic, and R2 is benzamido, anilino or phenylureido can be protected against the effects of formaldehyde by incorporating scavenger compounds of the formulae
<CHEM>
wherein, X1 to X6 each represents oxygen or imino, R3, R4, R7, R8, R10 and R11 each represent hydrogen, acyl or alkyl and R5 and R6 each represent @hydrogen@, hydroxyl group, amino group, a ureido group, an alkyl group, an aryl group, aryloxy group or an alkoxy group in which R5 and R6 may be coupled together to produce a 5 - 6 membered saturated carbocylic nucleus; and R9 represents imino group or an alkylidene group, and R12, R13, R14 and R15 each represent hydrogen, hydroxy group, amino group, an alkyl group, an alkoxy group, an aryl group or an aryloxy group, in which R12 and R13 and R14 and R15 each may be respectively coupled to each other to produce a 5 - 6 membered saturated carbocyclic nucleus, R16 and R17 each represent hydrogen, an alkyl group or an aryl group; and A represents -NH(CH2)m -NHCO- in which the nitrogen atom couples to carbon atom of C=X6 in Formula [IID] and m represents an integer of 1 or 2, or -NHCO- in which the nitrogen atom couples to carbon atom of C=X6 in Formula [IID]. </p> |
