871809-93-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 871809-93-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,7,1,8,0 and 9 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 871809-93:
(8*8)+(7*7)+(6*1)+(5*8)+(4*0)+(3*9)+(2*9)+(1*3)=207
207 % 10 = 7
So 871809-93-7 is a valid CAS Registry Number.

Heterocyclization involving benzylic C(sp3)-H functionalization enabled by visible light photoredox catalysis

Pandey, Ganesh,Laha, Ramkrishna,Mondal, Pradip Kumar

supporting information, p. 9689 - 9692 (2019/08/15)

A general and efficient method for heterocyclization involving benzylic C(sp3)-H functionalization enabled by visible light photoredox catalysis to access a wide range of structurally diverse oxygen as well as nitrogen heterocycles up to a gram scale is reported. The potential application of this new methodology is demonstrated by the total synthesis of (-)-codonopsinine and (+)-centrolobine. Herein it is proposed that selectfluor, unlike a fluorinating reagent, acts as an oxidative quencher and a hydrogen radical acceptor.

Lipase-catalyzed resolution of 1-[4-(benzyloxy)phenyl]hex-5-en-3-ol: Synthesis of (-)-centrolobine

Tadiparthi, Krishnaji,Raghavendra,Kamal, Ahmed

, p. 2321 - 2326 (2017/10/06)

A practical and efficient method for the preparation of homoallylic alcohol and its successful enzymatic resolution has been developed. This lipase-catalyzed resolution process has been optimized with respect to different lipases and solvents. Moreover, M

Enantioselective synthesis and absolute configurations of aculeatins A, B, D, and 6-epi-aculeatin D

álvarez-Bercedo, Paula,Falomir, Eva,Carda, Miguel,Marco

, p. 9641 - 9649 (2007/10/03)

The three naturally occurring, bioactive spiroacetals aculeatins A, B, and D, as well as the non-natural 6-epi-aculeatin D have been synthesized for the first time in enantiopure form using an asymmetric allylation as the only chirality source. A further
