Dimethyl 3-cyanopyrrolo[2,1-a]isoquinoline-1,2-dicarboxylate is a complex organic compound with the molecular formula C16H11N3O4. It is characterized by a pyrrolo[2,1-a]isoquinoline core, which is a fused ring system consisting of a pyrrole and an isoquinoline. The molecule features a cyano group (-CN) at the 3-position, and two carboxyl groups (-COOH) at the 1 and 2 positions, which are esterified with two methyl groups (-CH3), forming dimethyl esters. dimethyl 3-cyanopyrrolo[2,1-a]isoquinoline-1,2-dicarboxylate is known for its potential applications in the synthesis of various pharmaceuticals and agrochemicals due to its unique structure and reactivity. It is typically synthesized through multi-step organic reactions and is used as an intermediate in the preparation of more complex molecules. The compound's properties, such as its solubility and stability, can be influenced by the presence of the cyano and ester groups, making it a versatile building block in organic synthesis.

Check Digit Verification of cas no

The CAS Registry Mumber 3463-90-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,4,6 and 3 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 3463-90:
(6*3)+(5*4)+(4*6)+(3*3)+(2*9)+(1*0)=89
89 % 10 = 9
So 3463-90-9 is a valid CAS Registry Number.

Regioselectivity in the 1,3-Dipolar Cycloaddition Reaction of Unsymmetric Pyridinium Dicyanomethylides with Dimethyl Acetylenedicarboxylate and Methyl Propiolate: An Example of Dipole-Dipole Control of Regioselectivity?

Matsumoto, Kiyoshi,Ikemi, Yukio,Konishi, Hideyuki,Shi, Xiao-lan,Uchida, Takane,Aoyama, Kinuyo

, p. 689 - 692 (2007/10/02)

A study of the cycloaddition behavior of a series of unsymmetric pyridinium dicyanomethylides with dimethyl acetylenedicarboxylate and methyl propiolate has been carried out.The 1,3-dipolar cycloaddition proceeds in good yield with high regioselectivity to produce the corresponding indolizines and 1:1 adducts.The reactions of isoquinolinium dicyanomethylide follow frontier orbital predictions.In contrast, polar 3-substituted pyridinium dicyanomethylides gave predominantly the corresponding 8-isomers regardless of the substituents.The results can be explained by dipole-dipole interactions.
