2. Isopropenylmagnesium bromide (iPrMgBr) solution (0.5 M in THF) has been used in the Grignard reaction, a key step the in preparation of zofenoprilat and (S)-(?)-phosphonotrixin. It can also be used for the regioselective ring opening of an optically active epoxy alcohol in the total synthesis of (+)-desepoxyasperdiol.
General Description
This product, 1.0 M in 2-methyltetrahydrofuran aligns with Safer Solvents and Auxiliaries, Use of Renewable Feedstocks and Inherently Safer Chemistry for Accident Prevention.
Check Digit Verification of cas no
The CAS Registry Mumber 13291-18-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,2,9 and 1 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 13291-18:
(7*1)+(6*3)+(5*2)+(4*9)+(3*1)+(2*1)+(1*8)=84
84 % 10 = 4
So 13291-18-4 is a valid CAS Registry Number.

Domino electrocyclization/azide-capture/Schmidt rearrangement of dienones: One-step synthesis of dihydropyridones from simple building blocks
Song, Dong,Rostami, Ali,West
, p. 12019 - 12022 (2008/03/17)
Simple 1,4-dien-3-ones undergo Lewis acid-catalyzed Nazarov electrocyclization and intermolecular trapping by various azides to furnish 3,4-dihydropyridin-2-ones in moderate to good yields. The reaction is proposed to proceed via nucleophilic trapping of
Novel access to neopentyl-type halogenated cyclopentanoids via olefinic cyclobutanols
Nemoto, Hideo,Shiraki, Motohiro,Fukumoto, Keiichiro
, p. 1347 - 1348 (2007/10/03)
The iodonium ion-mediated ring expansion of olefinic cyclobutanols 20, 21, and 25 gave mixtures of iodoalkylated cyclopentanones 33a-c and 34a-c. On the other hand, the same reaction of 29, 30, and 32 stereoselectively afforded iodoalkylated cyclopentanon
