Paragraph 0049; 0054; 0055, (2018/06/04)
The present invention discloses a N-(2-guanidino-ethylimino)-morpholine hapten based on thiotriazinone structure restrictiveness, an artificial antigen, an antibody and an application. The structure of the N-(2-guanidino-ethylimino)-morpholine hapten is represented by a formula I shown in the description, wherein R is -H and -CH3. The N-(2-guanidino-ethylimino)-morpholine artificial antigen and antibody are prepared base on the hapten, and the artificial antigen and antibody have high detection efficiency and simple operation to N-(2-guanidino-ethylimino)-morpholine, and can be used in enzyme-linked immunosorbent assay rapid detection of the N-(2-guanidino-ethylimino)-morpholine; and the antigen and the antibody have a simple synthetic process, lower costs, and good application prospects.
Regioselective synthesis of pyrimido[1,2-a][1,3,5]triazin-6-ones via reaction of 1-(6-oxo-1,6-dihydropyrimidin-2-yl)guanidines with triethylorthoacetate: Observation of an unexpected rearrangement

A novel thermal rearrangement, involving pyrimidine ring opening and subsequent ring closure leading to recyclization of the system, was identified in the reaction of (6-oxo-1,6-dihydropyrimidin-2-yl)guanidines 3 (where NR 1R2 = NH2, NH alkyl, NH aralkyl, NHCH 2Ph(R)) with triethyl orthoacetate, affording 4-substituted-2-methyl- 6H-pyrimido[1,2-a][1,3,5]triazin-6-ones 6 and their ring opened products. However, no such rearrangement was observed with (6-oxo-1,6-dihydropyrimidin-2- yl)guanidines 3 bearing a tertiary amino or anilino substituent (i.e. where NR1R2 = N(CH3)2, indoline, morpholino, NHAr). As expected, 2-substituted-4-methyl-6H-pyrimido[1,2-a][1,3,5] triazin-6-ones 4 were obtained as the final products. Experimental structural determination and theoretical studies were carried out to get an understanding of the observed thermal rearrangement. In addition, an attempt to obtain similar pyrimido[1,2-a][1,3,5]triazin-6-ones using N,N-dimethylacetamide dimethyl acetal (DMA-DMA) as one carbon inserting synthon had furnished triazine ring annulated product 14 bearing N,N-dimethyl enamino substituent at position 4 as a result of further reaction with a second molecule of DMA-DMA.
