77657-90-0 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 77657-90-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,6,5 and 7 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 77657-90:
(7*7)+(6*7)+(5*6)+(4*5)+(3*7)+(2*9)+(1*0)=180
180 % 10 = 0
So 77657-90-0 is a valid CAS Registry Number.

Bioinspired Divergent Oxidative Cyclization from Strictosidine and Vincoside Derivatives: Second-Generation Total Synthesis of (?)-Cymoside and Access to an Original Hexacyclic-Fused Furo[3,2-b]indoline

Dou, Yingchao,Kouklovsky, Cyrille,Vincent, Guillaume

, p. 17190 - 17194 (2020/12/01)

The second-generation synthesis of (?)-cymoside as well as the formation of a new hexacyclic-fused furo[3,2-b]indoline framework is reported. After a Pictet–Spengler condensation between secologanin tetraacetate and tryptamine, the course of the cyclization of the 7-hydroxyindolenine intermediate, generated by oxidation with an oxaziridine, depended on the stereochemistry of the 3-position. The 3-(S)-strictosidine stereochemistry delivered efficiently the scaffold of cymoside via intramolecular coupling with the C16–C17 enol ether, while the 3-(R)-vincoside stereochemistry directed towards the reaction with the C18–C19 terminal alkene and the formation of the unexpected caged compound.

1,5-Hydrogen transfers from carbon to N-tributyltin substituted nitrogen

Kim, Sunggak,Yeon, Kyu Man,Yoon, Kwang Sub

, p. 3919 - 3922 (2007/10/03)

1,5-H transfers from carbon to N-tributyltin substituted nitrogen proceeded smoothly and were much more efficient than 1,5-H transfers from carbon to ordinary nitrogen. 1,5-Tribuyltin group transfer from carbon to nitrogen and intramolecular addition of an aminyl radical to a nitrile group were also observed for the first time.
