Paragraph 0028-0029; 0058-0059, (2021/10/05)
The invention provides a 2,4,6-trisubstituted-1,3,5-s-triazine compound as well as preparation and application thereof, and biguanide or dimethyl biguanide hydrochloride is used as an initial raw material to react with a cyano compound under an alkaline condition to prepare the 2,4,6-trisubstituted-1,3,5-s-triazine compound. The invention provides a simple and convenient synthetic method of a 2,4,6-trisubstituted-1,3,5-s-triazine compound, and the compound provided by the invention can be applied to preparation of an anti-myelogenous leukemia medicine, namely an enasidenib medicine. Compared with the prior art, the method for preparing the enasidenib has the advantages that two-step reaction is reduced, the use of a halogenating reagent is avoided, and the method is a green and environment-friendly chemical process. The structural formula I is shown in the specification.

Iridium-on-phosphorus-doped porous organic polymers (POP?Ir) were developed by anchoring simple iridium onto the skeleton of porous organic polymers through coordination bonds. This POP?Ir catalyst, which was thoroughly characterized by means of EDS, SEM, TEM, XRD, XPS, and FT-IR, revealed excellent catalytic activity for the reaction of diphenyl phosphinamide with benzyl alcohols through borrowing hydrogen strategy and acceptorless dehydrogenation with wide functional group tolerance. Moreover, this POP?Ir catalyst could be simply recovered and reused for at least five times without a significant loss of activity, and revealed considerable application prospects. The mechanism was investigated to further understand this POP?Ir catalytic system and transformations. Overall, the POP?Ir catalytic system has shown high activity and reusability in the borrowing hydrogen reaction between diphenyl phosphinamides and benzyl alcohols. (Figure presented.).
