378759-67-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 378759-67-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,7,8,7,5 and 9 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 378759-67:
(8*3)+(7*7)+(6*8)+(5*7)+(4*5)+(3*9)+(2*6)+(1*7)=222
222 % 10 = 2
So 378759-67-2 is a valid CAS Registry Number.

Tandem Copper-Catalyzed Regioselective N-Arylation-Aza-Michael Addition: Synthesis of Tetracyclic 5 H-Benzothiazolo[3,2- a]quinazoline Derivatives

Honnanayakanavar, Jyoti M.,Harish, Battu,Nanubolu, Jagadeesh Babu,Suresh, Surisetti

supporting information, p. 8780 - 8791 (2020/08/28)

A copper-catalyzed tandem process integrating regioselective N-arylation, followed by aza-Michael addition, is disclosed using 2-aminobenzothiazoles and ortho-halo cinnamic acid congeners. This process generated diverse tetracyclic 5H-benzothiazolo[3,2-a]quinazoline derivatives in moderate to good yields. The present tandem reaction appears to proceed through concomitant ring opening of 2-aminobenzothiazole and S-arylation to give the ortho-cyanamide-substituted diaryl thioether intermediate. The thus generated intermediate likely undergoes an unprecedented Truce-Smiles-type rearrangement involving S- to N-aryl migration, followed by reformation of the thiazole ring and intramolecular aza-Michael addition to furnish the title products.

Gold catalyzed Heck-coupling of arenediazonium o-benzenedisulfonimides

Barbero, Margherita,Dughera, Stefano

, p. 295 - 301 (2018/01/12)

Diazonium salts, and precisely arenediazonium o-benzenedisulfonimides, have been used for the first time as efficient electrophilic partners in gold catalyzed Heck-coupling reactions. The synthetic protocol was general, easy and gave the target products in satisfactory yields. Mechanistic insights revealed the fundamental roles of the o-benzenedisulfonimide anion as an electron transfer agent thath promotes a radical pathway that does not require the presence of photocatalysts or external oxidants.
