144707-40-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 144707-40-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,4,7,0 and 7 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 144707-40:
(8*1)+(7*4)+(6*4)+(5*7)+(4*0)+(3*7)+(2*4)+(1*0)=124
124 % 10 = 4
So 144707-40-4 is a valid CAS Registry Number.

Total Synthesis of (±)-Taiwaniaquinol F and Related Taiwaniaquinoids

Kakde, Badrinath N.,Kumari, Pooja,Bisai, Alakesh

, p. 9889 - 9899 (2015)

Total synthesis of (±)-taiwaniaquinol F (1a) has been accomplished via an efficient Lewis acid-catalyzed Nazarov-type cyclization of aryldiallylcarbinols (±)-2e derived from safranal 7. The methodology works under mild conditions using only 2 mol % of met

Hyperconjomer stereocontrol of cationic polyene cyclisations

Rodger, Robert T.,Graham, Marlowe S.,McErlean, Christopher S. P.

, p. 8551 - 8560 (2019/10/02)

Polyene cyclisations are a powerful method for the direct generation of molecular complexity. This paper describes the use of computational methods to investigate the stereoselectivity of cationic polyene cyclisations of geranylbenzene derivatives. The ou

Approach to Merosesquiterpenes via Lewis Acid Catalyzed Nazarov-Type Cyclization: Total Synthesis of Akaol A

Kakde, Badrinath N.,Kumar, Nivesh,Mondal, Pradip Kumar,Bisai, Alakesh

, p. 1752 - 1755 (2016/05/19)

A Lewis acid catalyzed Nazarov-type cyclization of arylvinylcarbinol has been developed for the asymmetric synthesis of carbotetracyclic core of merosesquiterpenes. The reaction works only in the presence of 2 mol % of Sn(OTf)2 and Bi(OTf)3 in dichloroethane under elevated temperature. The methodology offers the synthesis of a variety of enantioenriched arylvinylcarbinols from commercially available (3aR)-sclareolide 9 in six steps with an eventual concise total synthesis of marine sesquiterpene quinol, akaol A (1a).

Total syntheses of (±)-taiwaniaquinol D and (±)-taiwaniaquinone D via a key Lewis acid-catalyzed Nazarov type cyclization

Kakde, Badrinath N.,Parida, Amarchand,Kumari, Pooja,Bisai, Alakesh

, p. 3179 - 3184 (2016/07/06)

Total syntheses of structurally intriguing taiwaniaquinoids viz (±)-taiwaniaquinol D (1e) and (±)-taiwaniaquinone D (1h) have been disclosed via a key Lewis acid catalyzed Nazarov type cyclization of arylvinylcarbinols.

A formal total synthesis of salvadione

Maier, Martin E.,Bayer, Alexander

, p. 4034 - 4043 (2007/10/03)

The tricyclic 6-7-6 core structure of the triterpene salvadione (1) was obtained in an efficient manner from the aryl bromide 16 and the alkyl iodide 35 carrying a methylenecyclohexane group at the terminus. Alkylation of the anion derived from 16 with th
