(3aR,4R,9aS,9bS)-4-Benzoyl-6-methyl-2-p-tolyl-3a,4,9a,9b-tetrahydro-pyrrolo[3,4-a]indolizine-1,3-dione is a complex organic compound with a unique molecular structure. It is characterized by a pyrrolo[3,4-a]indolizine core, which is a fused ring system consisting of a pyrrole and an indolizine. The compound features a benzoyl group at the 4-position, a methyl group at the 6-position, and a p-tolyl group at the 2-position. The tetrahydro prefix indicates that the molecule has four hydrogen atoms added to the parent hydrocarbon structure, resulting in a more saturated and stable compound. The specific stereochemistry of the molecule is defined by the R and S configurations at the 3a, 4, 9a, and 9b positions, which influence the compound's physical and chemical properties. (3aR,4R,9aS,9bS)-4-Benzoyl-6-methyl-2-p-tolyl-3a,4,9a,9b-tetrahydro-pyrrolo[3,4-a]indolizine-1,3-dione is of interest in the field of organic chemistry and may have potential applications in pharmaceuticals or materials science due to its intricate structure and potential for molecular interactions.

Check Digit Verification of cas no

The CAS Registry Mumber 90650-46-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,6,5 and 0 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 90650-46:
(7*9)+(6*0)+(5*6)+(4*5)+(3*0)+(2*4)+(1*6)=127
127 % 10 = 7
So 90650-46-7 is a valid CAS Registry Number.

Stereochemical Study on 1,3-Dipolar Cycloaddition Reactions of Heteroaromatic N-Ylides with Symmetrically Substituted cis and trans Olefins

Tsuge, Otohiko,Kanemasa, Shuji,Takenaka, Shigeori

, p. 3137 - 3157 (2007/10/02)

Stereochemistry of the cycloadditions of twenty-four heteroaromatic N-ylides with several symmetrically substituted cis and trans olefins has been investigated.Cyclic and acyclic cis olefins cycloadd to the anti form of the ylides in a highly endo-selective manner giving almost quantitative yields of stereospecific endo 3+2 cycloadducts.N-Ylides stabilized with a substituent of carbonyl type react with trans olefins to form mostly two stereoisomeric 3+2 cycloadducts to the anti form of the ylides.In most cases, they undergo the stereospecific interconversion through a retro cycloaddition process, the isomer ratios and the easiness of transfromation depending upon the nature and size of substituents on the five-membered ring which has been built up in the cycloaddition step.On the other hand, N-ylides stabilized with a substituent of noncarbonyl type react with trans olefins to give stereospecific and stereoselective 3+2 cycloadducts as single isomers which are assigned as the cycloadducts to the syn form of the ylides.

STEREOSELECTIVE HYDROALKYLIDENATION OF OLEFIN WITH PYRIDINIUM METHYLIDES

Tsuge, Otohiko,Kanemasa, Shuji,Takenaka, Shigeori,Kuraoka, Satoru

, p. 465 - 468 (2007/10/02)

Acid-catalyzed elimination of pyridine from the stereoselective cycloadducts between electron-deficient olefins and pyridinium methylides with ylide-stabilizing substituents offers a new type of C-C bond formation.
