1-(5-bromofuran-2-yl)-3-phenylprop-2-yn-1-one is a complex organic compound characterized by a unique molecular structure. It features a 2-yn-1-one backbone, which consists of a propargyl group (a three-carbon chain with a triple bond) and a carbonyl group (a double-bonded oxygen). The compound is further distinguished by the presence of a 5-bromofuran-2-yl group, which adds a bromine atom to a furan ring, a five-membered aromatic ring with one oxygen atom. Additionally, a phenyl group (a benzene ring) is attached to the propargyl backbone, enhancing the compound's aromatic character. This chemical is primarily used in the synthesis of various pharmaceuticals and other organic compounds due to its reactive functional groups and unique structural features.

Check Digit Verification of cas no

The CAS Registry Mumber 2976-02-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,9,7 and 6 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 2976-02:
(6*2)+(5*9)+(4*7)+(3*6)+(2*0)+(1*2)=105
105 % 10 = 5
So 2976-02-5 is a valid CAS Registry Number.

Stitching Ynones with Nitromethanes: Domino Synthesis of Functionally Enriched Benzofurans and Benzothiophenes

Mehta, Goverdhan,Nerella, Sharanya,Pabbaraja, Srihari,Singh, Shweta

, p. 12093 - 12106 (2021/09/13)

A convenient one-pot benzannulation of regioisomeric 2- or 3-substituted furan and thiophene ynones with a range of nitromethanes has been discovered to directly access densely and diversely functionalized benzofurans and benzothiophenes. In this protocol, the nitro group in nitromethanes functions as recursive carbanion activator to setup tandem Michael addition-6π-electrocyclization, and its eventual sacrificial elimination facilitates aromatization and overall benzannulation. This benzannulation was also explored with furan/thiophene based o-halo ynones wherein a Michael addition-SNAr process operates and nitromethanes leave their imprint to deliver nitro substituted benzo-furans and -thiophenes.

PALLADIUM-CATALYZED COUPLINGS OF HALOFURANS WITH ACTIVATED ALKENES AND TERMINAL ALKYNES. A SHORT SYNTHESIS OF DIHYDROWYERONE

Crisp, Geoffrey T.,O'Donoghue, Ana I.

, p. 1745 - 1758 (2007/10/02)

The palladium-catalyzed coupling of bromofurans with activated alkenes and of furanoyl chlorides with either terminal alkynes or alkynyl stannanes gave good yields of the corresponding vinyl furans and alkynyl ketones.These studies culminated in a short s
