5,7-dihydrofuro[3,4-b]pyridine is a heterocyclic compound characterized by a unique structure that fuses a dihydrofuran ring with a pyridine ring. 5,7-dihydrofuro<3,4-b>pyridine is of interest in organic chemistry and medicinal chemistry due to its potential applications in the development of pharmaceuticals and other chemical products. The fusion of these two rings creates a stable and versatile scaffold that can be further functionalized to explore a range of chemical properties and biological activities. While the specific applications and properties of 5,7-dihydrofuro[3,4-b]pyridine can vary widely depending on the substituents and functional groups attached to the core structure, the compound itself represents a promising starting point for the synthesis of more complex molecules with targeted therapeutic or chemical effects.

Check Digit Verification of cas no

The CAS Registry Mumber 6570-02-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,5,7 and 0 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 6570-02:
(6*6)+(5*5)+(4*7)+(3*0)+(2*0)+(1*2)=91
91 % 10 = 1
So 6570-02-1 is a valid CAS Registry Number.

INTRAMOLECULAR DIELS-ALDER REACTIONS OF QUATERNARY PYRAZINIUM SALTS AND PROTONATED PYRAZINIUM CATIONS. SYNTHESIS OF ANNELATED PYRIDINIUM SALTS AND ANNELATED PYRIDINES.

Geurtsen, Bart,Bie, Dick A. de,Plas, Henk C. van der

, p. 6519 - 6530 (1989)

Quaternization of alkynyl substituted pyrazines with triethyloxonium tetrafluoroborate in dichloromethane occurs exclusively at N-4 yielding 3-alkynyl-1-ethylpyrazinium salts, as shown by the 13C NMR data.Protonation of the same pyrazines with trifluoroacetic acid also occurs at N-4.The quaternary pyrazinium salts as well as the protonated pyrazines undergo an intramolecular Diels-Alder reaction under considerably milder conditions than the corresponding neutral pyrazines.The products of the reactions were -annelated quaternary pyridinium salts and -annelated protonated pyridinium cations, respectively.
