16347-56-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 16347-56-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,3,4 and 7 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 16347-56:
(7*1)+(6*6)+(5*3)+(4*4)+(3*7)+(2*5)+(1*6)=111
111 % 10 = 1
So 16347-56-1 is a valid CAS Registry Number.

Microwave-assisted [3+2] cycloaddition and suzuki-miyaura cross-coupling for a concise access to polyaromatic scaffolds

Hedou, Damien,Deau, Emmanuel,Dubouilh-Benard, Carole,Sanselme, Morgane,Martinet, Anthony,Chosson, Elizabeth,Levacher, Vincent,Besson, Thierry

, p. 7533 - 7545 (2013)

Novel 3-(prop-2-ynyl)pyrido[2,3-d]pyrimidin-4(3H)-ones and 3-(prop-2-ynyl)quinazolin-4(3H)-ones have been synthesized in a high-yielding microwave-assisted one-pot procedure. The one-pot sequence was conveniently extended to the synthesis of commercially unavailable 6-bromo-N 3-propargylpyrido[2,3-d]pyrimidinone by a regiocontrolled bromination with NBS. The synthetic scaffolds were successfully converted into triazoles by copper(I)-catalyzed [3+2] cycloaddition and substituted at the 6-position by Suzuki-Miyaura cross-coupling in high overall yields. A microwave-assisted one-pot sequential synthesis involving esterification, formylation, bromination, and cyclization of anthranilic and 2-aminonicotinic acid derivatives provides access to N3-propargylquinazolinones or -pyridopyrimidinones in high overall yields. Functionalization by [3+2] cycloaddition and Suzuki-Miyaura cross-coupling rapidly led to 48 novel polyaromatic heterocycles.

Visible-light induced copper(i)-catalyzed oxidative cyclization of: O -aminobenzamides with methanol and ethanol via HAT

Bhargava Reddy, Mandapati,Prasanth, Kesavan,Anandhan, Ramasamy

, p. 9601 - 9605 (2020/12/28)

The use of the in situ generated ligand-copper superoxo complex absorbing light energy to activate the alpha C(sp3)-H of MeOH and EtOH via the hydrogen atom transfer (HAT) process for the synthesis of quinazolinones by oxidative cyclization of alcohols with o-aminobenzamide has been investigated. The synthetic utility of this protocol offers an efficient synthesis of a quinazolinone intermediate for erlotinb (anti-cancer agent) and 30 examples were reported.

Selective Oxidative Cleavage of 3-Methylindoles with Primary Amines Affording Quinazolinones

He, Junhui,Dong, Jianyu,Su, Lebin,Wu, Shaofeng,Liu, Lixin,Yin, Shuang-Feng,Zhou, Yongbo

supporting information, p. 2522 - 2526 (2020/04/09)

A selective functionalization of C-C-C bonds toward N-C-O bonds is realized by an n-Bu4NI-catalyzed reaction of 3-methylindoles with primary amines using TBHP as the unique oxidant. The systematic process involves oxygenation, nitrogenation, ring-opening, and recyclization, affording a broad range of quinazolinones in good to excellent yields.
