147976-19-0 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 147976-19-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,7,9,7 and 6 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 147976-19:
(8*1)+(7*4)+(6*7)+(5*9)+(4*7)+(3*6)+(2*1)+(1*9)=180
180 % 10 = 0
So 147976-19-0 is a valid CAS Registry Number.

The influence of α-coordinating groups of aldehydes on E/Z-selectivity and the use of quaternary ammonium counter ions for enhanced E-selectivity in the Julia–Kocienski reaction

Rehman, Mintu,Surendran, Sravya,Siddavatam, Nagendra,Rajendar, Goreti

, p. 329 - 333 (2022/01/20)

Modified reaction conditions for improved E-selectivity of olefins in the Julia–Kocienski reaction of aldehydes having α-coordinating substituents are demonstrated. The chelating groups in aldehydes are expected to stabilize the syn-transition state with metal ions, whereas the weakly coordinating quaternary ammonium ions are devoid of all possible chelating interactions to enhance E-selectivity. A systematic investigation is presented to study the size of the neighbouring protecting groups of aldehydes and their chelation effect on E/Z-selectivity in the Julia–Kocienski reaction.

Diastereoselective Fluorocyclopropanation of Chiral Allylic Alcohols Using an α-Fluoroiodomethylzinc Carbenoid

Navuluri, Chandrasekhar,Charette, André B.

supporting information, p. 4288 - 4291 (2015/09/15)

Chiral fluorocyclopropyl carbinols were synthesized in high diastereoselectivities via a zinc mediated cyclopropanation reaction, using sec-allylic alcohols as simple building blocks. An enantioselective version of this transformation was achieved through

Synthesis of enantiomerically pure perhydrofuro[3,4-b]pyrans and perhydrofuro[3,4-b]furans

Tiecco, Marcello,Testaferri, Lorenzo,Bagnoli, Luana,Terlizzi, Raffaella,Temperini, Andrea,Marini, Francesca,Santi, Claudio,Scarponi, Catalina

, p. 1949 - 1955 (2007/10/03)

Olefinic diols, prepared from (R)-(+)-2,2-dimethyl-1,3-dioxolane-4- carboxaldehyde via olefination and hydrolysis, were converted into enantiomerically pure hydroxy substituted tetrahydrofuran derivatives by cyclization using N-phenylselenophthalimide and BF3. The PhSe group in the C-4 position of these tetrahydrofurans was then substituted by an allyl group using allyltributylstannane in the presence of AIBN. The selenium promoted cyclizations of the allyl tetrahydrofurans in which the OH and the allyl groups are trans to each other formed the enantiopure perhydrofuro[3,4-b]pyrans, while the cyclization of the allyl tetrahydrofurans in which the OH and the allyl groups are cis gave rise to the perhydrofuro[3,4-b]furans. These bicyclic products were finally deselenenylated with triphenyltin hydride and AIBN.
