28383-65-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 28383-65-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,3,8 and 3 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 28383-65:
(7*2)+(6*8)+(5*3)+(4*8)+(3*3)+(2*6)+(1*5)=135
135 % 10 = 5
So 28383-65-5 is a valid CAS Registry Number.

Br?nsted Acid Catalyzed (4 + 2) Cyclocondensation of 3-Substituted Indoles with Donor-Acceptor Cyclopropanes

Ortega, Alesandere,Uria, Uxue,Tejero, Tomás,Prieto, Liher,Reyes, Efraim,Merino, Pedro,Vicario, Jose L.

, p. 2326 - 2331 (2021)

Acylcyclopropanes are employed as useful donor-acceptor cyclopropanes that undergo formal (4 + 2) cyclocondensation with N-unprotected 3-substituted indoles in the presence of a Br?nsted acid catalyst. The reaction involves the simultaneous alkylation of both the N and C-2 positions of the indole and provides access to the 8,9-dihydropyrido[1,2-a]indole scaffold that is the central core of several biologically relevant indole alkaloids in excellent yields and good selectivities.

Rhodium(III)-catalyzed C-C bond formation of quinoline N-oxides at the C-8 position under mild conditions

Jeong, Jisu,Patel, Pitambar,Hwang, Heejun,Chang, Sukbok

, p. 4598 - 4601 (2014)

The Rh(III)-catalyzed C-8 selective direct alkylation and alkynylation of quinoline N-oxides has been developed. The reactions proceeded highly efficiently at room temperature over a broad range of substrates with excellent regioselectivity and functional group tolerance. This development demonstrates the synthetic utility of the N-oxide directing group as a stepping stone for remote C-H functionalization of quinolines.

Photoinduced Diverse Reactivity of Diazo Compounds with Nitrosoarenes

Roy, Sourav,Kumar, Gourav,Chatterjee, Indranil

, p. 6709 - 6713 (2021/09/08)

A diverse reactivity of diazo compounds with nitrosoarene in an oxygen-transfer process and a formal [2 + 2] cycloaddition is reported. Nitosoarene has been exploited as a mild oxygen source to oxidize an in situ generated carbene intermediate under visible-light irradiation. UV-light-mediated in situ generated ketenes react with nitosoarenes to deliver oxazetidine derivatives. These operationally simple processes exemplify a transition-metal-free and catalyst-free protocol to give structurally diverse α-ketoesters or oxazetidines.

Design, synthesis and anticancer activity of 5-aryl-4-(4-arylpiperazine-1-carbonyl)-1,2,3-thiadiazoles as microtubule-destabilizing agents

Wang, Chao,Wang, Zeyu,Gao, Minghuan,Li, Yuelin,Zhang, Yujing,Bao, Kai,Wu, Yingliang,Guan, Qi,Zuo, Daiying,Zhang, Weige

, (2020/12/21)

Hereby, we report our efforts on discovery and optimization of a new series of 5-aryl-4-(4-arylpiperazine-1-carbonyl)-1,2,3-thiadiazoles as new microtubule-destabilizing agents along our previous study. Guided by docking model analysis, we introduced the 1,2,3-thiadiazole moiety containing the hydrogen-bond acceptors as B-ring of XRP44X analogues. Extensive structure modifications were performed to investigate the detailed structure and activity relationships (SARs). Some compounds exhibited potent antiproliferative activities against three human cancer cell lines (SGC-7901, A549 and HeLa). The compound 5m exhibited the highest potency against the three cancer cell lines. The tubulin polymerization experiments indicated that compound 5m effectively inhibited the tubulin polymerization, and immunostaining assay revealed that it significantly disrupted microtubule dynamics. Moreover, cell cycle studies revealed that compound 5m dramatically arrested cell cycle progression at G2/M phase.
