The present invention provides compound of formula 1, or an isotopic form, a stereoisomer, a tautomer, a pharmaceutically acceptable salt, a solvate, a polymorph, a prodrug, S-oxide or N-oxide thereof. The invention also relates toprocesses for their preparation, to pharmaceutical compositions containing them and use of the compound of formula 1, in the treatment of diseases or disorders mediated by EZH2 (enhancer of zeste homolog 2), particularly cancer.
phosphine-catalyzed transformation has been developed for the synthesis of chiral cyclobutene triesters and fluorinated spirocyclic compounds. The strategy involved a P(III)/P(V) redox cycling process, via in situ reduction of phosphine oxide with phenylsilane. This catalytic methodology has enabled the enantioselective synthesis of functionalized cyclobutenes (24 examples, up to 94% ee). On the occasion of the

The invention relates to a process for producing a trivalent hexadentate ortho-metallated iridium complex with an iridium compound and a coordination compound as starting materials, which is characterized in that a monovalent iridium dinulear complex represented by the following formula (I)is used:(wherein A represents a non-conjugated diene compound; and X represents a halogen atom).According to the invention, it is possible to carry out the successive reactions in the same reaction vessel (i.e., one-pot reaction) by using the complex produced in the above process in the next step without isolation and purification.

2-Acylcycloalkanones having polyfluoroalkyl groups react with guanidine, urea, thiourea, methylisothiourea, benzamidine, guanylthiourea, dicyanodiamide, and trifluoroacetylurea by Lewis-acid catalysis to form the corresponding 5,6-oligomethylene pyrimidines. A decrease in the yields along with increase of polyfluoroalkyl substituent length in the molecule of the starting 1,3-diketone was observed in the case of reagents with lower nucleophilicity (urea, thiourea, dicyanodiamide). The pyrimidines obtained from aromatic aldehydes showed E-configuration with respect to the arylidene double bond. Tautomeric structures as a function of the substituent in 2 position in the pyrimidine ring both in liquid and solid state were investigated by X-ray diffraction, IR and NMR spectroscopy.
