518-77-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 518-77-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,1 and 8 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 518-77:
(5*5)+(4*1)+(3*8)+(2*7)+(1*7)=74
74 % 10 = 4
So 518-77-4 is a valid CAS Registry Number.

Three-Step Catalytic Asymmetric Total Syntheses of 13-Methyltetrahydroprotoberberine Alkaloids

Zhou, Shiqiang,Tong, Rongbiao

, p. 1594 - 1597 (2017/04/13)

(S,R)-N-PINAP was identified to be the chiral ligand for highly enantioselective CuI-catalyzed reaction of tetrahydroisoquinolines (THIQs), alkynes, and 2-bromobenzaldehyde derivatives. This enables us to accomplish the first asymmetric total synthesis of 12 natural 13-methyltetrahydroprotoberberine (13-MeTHPB) alkaloids in only three catalytic steps with 47-64% overall yields. In addition, the Pd-catalyzed reductive Heck cyclization was successfully extended to three Pd-catalyzed domino reactions (Heck/Suzuki, Heck/Sonogashira, and Heck/Heck), which greatly expands the synthetic utility of this catalytic strategy and allows expeditious access to 13-substituted tetrahydroprotoberberines for further bioactivity evaluation.
