Compounds of formula I wherein when X3 is NH and derivatives and O, X4 is a single bond, and X5 is N and CR5, and R1R2 are taken together to form (un)substituted benzene ring; when X3 is CR3c, X4 is N and CR4, and X5 is N and CR5, and R1R2 are taken together to form (un)substituted furan, (un)substituted pyrazole or (un)substituted benzene ring; L is O when A is CHR6; L is a bond when n is absent and CHR6; R3c and N are independently H, halo, OH, CN, (un)substituted C3-6 cycloalkyl, etc.; R6 is H; R5R6 can be taken together to form ethane-1,2-diyl bridge; R7 and R8 are independently H and (un)substituted C1-4 alkyl; R9 is H and (un)substituted C1-4 alkyl; R10 is azetidin-1-ylmethyl, pyrrolidin-1-ylmethyl and heterocyclyl; and pharmaceutically acceptable salts thereof, are claimed. Example compound II was prepared by amidation of 2-(1-(tert-butoxycarbonyl)pyrrolidin-2-yl)acetic acid with 2-(1,7-dimethyl-1H-indazol-3-yl)propan-2-amine followed by hydrolysis; the resulting 7-(2-(1,7-dimethyl-1H-indazol-3-yl)propan-2-yl)-2-(pyrrolidin-2- yl)acetamide underwent reductive methylation with formaldehyde to give compound II. The invention compounds were evaluated for their SSTR4 inhibitory activity. From the assay, it was determined that compound II exhibited pEC50 value of 8.2 and pIC50 value of 7.2. The experimental process involved the reaction of 5-Methylisoquinoline-1-carbonitrile(cas: 1367744-24-8).Application In Synthesis of 5-Methylisoquinoline-1-carbonitrile

On March 1, 2022, Zhou, Chao; Gan, Qi-Chao; Zhou, Tai-Ping; Lei, Tao; Ye, Chen; He, Xiao-Jun; Chen, Bin; Lu, Heng; Wan, Qian; Liao, Rong-Zhen; Tung, Chen-Ho; Wu, Li-Zhu published an article.Product Details of 1367744-24-8 The title of the article was Site-Selective N-1 and C-3 Heteroarylation of Indole with Heteroarylnitriles by Organocatalysis under Visible Light. And the article contained the following:

Site-selective N-1 and C-3 arylation of indole was sought after because of the prevalent application of arylindoles and the intricate reactivities associated with the multiple sites of the N-unsubstituted indole. Represented herein is the first regioselective heteroarylation of indole via a radical-radical cross-coupling by visible-light irradiation Steady and time-resolved spectroscopic and computational studies revealed that the hydrogen-bonding interaction of organic base and its conjugated acid, namely with indole and heteroarylnitrile, determined the reaction pathway, which underwent either proton-coupled electron-transfer or energy-transfer for the subsequent radical-radical cross-coupling, leading to the regioselective formation of C-3 and N-1 heteroarylation of indoles, resp. The parallel methodologies for regioisomeric N-1 and C-3 heteroaryl indoles with good functional group compatibility was applied to large-scale synthesis and late-stage derivatization of bioactive compounds under extremely mild reaction conditions. The experimental process involved the reaction of 5-Methylisoquinoline-1-carbonitrile(cas: 1367744-24-8).Product Details of 1367744-24-8
