16619-51-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 16619-51-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,6,1 and 9 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 16619-51:
(7*1)+(6*6)+(5*6)+(4*1)+(3*9)+(2*5)+(1*1)=115
115 % 10 = 5
So 16619-51-5 is a valid CAS Registry Number.

Visible Light Promoted Chan-Lam Reaction and Cycloaddition to Prepare Chromeno[4,3-c]isoxazolidines in One-Pot Reaction

Huang, Bing-Qing,Ma, Xiao-Pan,Mo, Dong-Liang,Zhao, Jie,Zhu, Bin-Can

, p. 4575 - 4581 (2021/08/13)

A variety of chromeno[4,3-c]isoxazolidines were prepared in good yields through visible light promoted Chan-Lam reaction and [3+2] cycloaddition cascade reaction in one pot. Mechanistic studies showed that visible light promoted both Chan-Lam reaction and cycloaddition. The obtained products were converted to various useful chromenone derivatives. Moreover, the reaction was easily performed at gram scales with the purification of products without column chromatography and used to efficiently synthesize estrone-derived chromeno[4,3-c]isoxazolidine. (Figure presented.).

Iodine-mediated direct synthesis of 3-iodoflavones

Patil, Avinash M.,Kamble, Dayanand A.,Lokhande, Pradeep D.

, p. 1299 - 1307 (2018/04/05)

Molecular iodine has been used for the regioselective, one pot, direct synthesis of 3-iodoflavones from 2′-allyloxy chalcones, 2′-hydroxy chalcones and flavones. Allyl deprotection, cyclization dehydrogenation and α-iodination of 2′-allyloxychalcones has been achieved in a single step to offer 3-iodoflavones.

Sodium-iodoxybenzoate mediated highly chemoselective aziridination of olefins

Bakthavachalam, Ananthan,Chuang, Hui-Chun,Yan, Tu-Hsin

, p. 5884 - 5894 (2015/03/30)

Herein we utilized, for the first time, sodium 2-iodoxybenzoate as a highly specific oxidant for PhthNH2 to create a highly chemoselective aziridination reagent. This method efficiently effects aziridination of electron-rich, electron-deficient, allylic alcohol and alkenyl bromide C=C bonds in good to excellent yields. Inter and intramolecular chemoselectivity was demonstrated between electron-rich and electron-deficient alkenes by using this efficient and metal free protocol.
