3-Pentanone, 2-[[(1,1-dimethylethyl)diphenylsilyl]oxy]-4-(triphenylphosphoranylidene)-, (R)- is a complex organic compound characterized by its unique molecular structure. It is a chiral ketone with a five-carbon chain, where the third carbon is a ketone group. The molecule features a (1,1-dimethylethyl)diphenylsilyl group attached to the second carbon, which is a bulky, electron-donating group that can influence the reactivity and stereochemistry of the molecule. Additionally, a triphenylphosphoranylidene group is present at the fourth carbon, which is a phosphorus-containing moiety that can participate in various chemical reactions. The (R)- configuration indicates the specific arrangement of atoms in the molecule, which is crucial for its stereochemistry and potential biological activity. 3-Pentanone, 2-[[(1,1-dimethylethyl)diphenylsilyl]oxy]-4-(triphenylphosphoranylidene)-, (R)- is of interest in organic chemistry and may have applications in the synthesis of pharmaceuticals and other specialty chemicals due to its unique structural features.

90246-35-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 90246-35-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,2,4 and 6 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 90246-35:
(7*9)+(6*0)+(5*2)+(4*4)+(3*6)+(2*3)+(1*5)=118
118 % 10 = 8
So 90246-35-8 is a valid CAS Registry Number.

Efficient total syntheses of pumiliotoxins A and B. Applications of iodide-promoted iminium ion-alkyne cyclizations in alkaloid construction

Lin, Nan-Horng,Overman, Larry E.,Rabinowitz, Michael H.,Robinson, Leslie A.,Sharp, Matthew J.,Zablocki, Jeffery

, p. 9062 - 9072 (2007/10/03)

A practical route for the total synthesis of pumiliotoxin A alkaloids is described. The central step is formation of the piperidine ring and establishment of the (Z)-alkylidene side chain by an iodide-promoted iminium ion-alkyne cyclization. The total syn
