General Description

3,5-Dichloroindole is a chemical compound that belongs to the class of indole derivatives, which are commonly found in a variety of natural products and pharmaceuticals. It is a highly chlorinated form of indole, with chlorine atoms attached at the 3 and 5 positions on the aromatic ring. 3,5-Dichloroindole has been studied for its potential applications in the synthesis of pharmaceuticals and agrochemicals, as well as its use as a building block for organic synthesis. Its unique structure and reactivity make it a valuable intermediate in the production of diverse chemical compounds. Additionally, its potential biological activities and potential toxicological effects have also been the subject of research.

Check Digit Verification of cas no

The CAS Registry Mumber 120258-33-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,0,2,5 and 8 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 120258-33:
(8*1)+(7*2)+(6*0)+(5*2)+(4*5)+(3*8)+(2*3)+(1*3)=85
85 % 10 = 5
So 120258-33-5 is a valid CAS Registry Number.

Biomimetic total synthesis of malbrancheamide and malbrancheamide B

Miller, Kenneth A.,Welche, Timothy R.,Greshock, Thomas J.,Ding, Yousong,Sherman, David H.,Williams, Robert M.

, p. 3116 - 3119 (2008)

(Chemical Equation Presented) The biomimetic total syntheses of both malbrancheamide and malbrancheamide B are reported. The synthesis of the two monochloro species enabled the structure of malbrancheamide B to be unambiguously assigned. The syntheses each feature an intramolecular Diels-Alder reaction of a 5-hydroxypyrazin-2(1H)-one to construct the bicyclo[2.2.2] diazaoctane core, which has also been proposed as the biosynthetic route to these compounds.

Ni-NiO heterojunctions: a versatile nanocatalyst for regioselective halogenation and oxidative esterification of aromatics

Bhardwaj, Nivedita,Singh, Ajit Kumar,Tripathi, Nancy,Goel, Bharat,Indra, Arindam,Jain, Shreyans K.

, p. 14177 - 14183 (2021/08/16)

Herein, we report a facile method for the synthesis of Ni-NiO heterojunction nanoparticles, which we utilized for the nuclear halogenation reaction of phenol and substituted phenols usingN-bromosuccinimide (NBS). A remarkablepara-selectivity was achieved for the halogenated products under semi-aqueous conditions. Interestingly, blocking of thepara-position of phenol offeredortho-selective halogenation. In addition, the Ni-NiO nanoparticles catalyzed the oxidative esterification of carbonyl compounds with alcohol, diol or dithiol in the presence of a catalytic amount of NBS. It was observed that the aromatic carbonyls substituted with an electron-donating group favoured nuclear halogenation, whereas an electron-withdrawing group substitution in carbonyl compounds facilitated the oxidation reaction. In addition, the catalyst was magnetically separated and recycled 10 times. The tuned electronic structure at the Ni-NiO heterojunction controlled selectivity and activity as no suchpara-selectivity was observed with commercially available NiO or Ni nanoparticles.
