18733-07-8 Usage

Preparation

Preparation from 2-iodophenyl p-anisate on treatment with n-butyllithium in a mixture of ethyl ether, hexane and tetrahydrofuran at ?70° for 2 h, followed by treatment with saturated aqueous ammonium chloride (<18%).

Check Digit Verification of cas no

The CAS Registry Mumber 18733-07-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,7,3 and 3 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 18733-07:
(7*1)+(6*8)+(5*7)+(4*3)+(3*3)+(2*0)+(1*7)=118
118 % 10 = 8
So 18733-07-8 is a valid CAS Registry Number.

Water-Tolerant ortho-Acylation of Phenols

Dong, Shuang-Feng,Gao, Zhi-Yuan,He, Yu,Liu, Xu,Loh, Teck-Peng,Tian, Jie-Sheng,Wu, Peng

, p. 6594 - 6598 (2021/09/02)

A metal-free, water-tolerant, and one-pot process for ortho-acylation of phenols promoted by the iodine source/hydrogen peroxide system has been developed. This transformation undergoes ether formation, iodocyclization, C-C bond cleavage, and oxidative hydrolysis in a one-step manner, which is supported by control experiments.

Asymmetric Transfer Hydrogenation of o-Hydroxyphenyl Ketones: Utilizing Directing Effects That Optimize the Asymmetric Synthesis of Challenging Alcohols

Clarkson, Guy J.,Wills, Martin,Zheng, Ye

supporting information, (2020/05/05)

A systematic range of o-hydroxyphenyl ketones were reduced under asymmetric transfer hydrogenation conditions using the C3-tethered catalyst 2. Two directing effects, i.e., an o-hydroxyphenyl coupled to a bulky aromatic on the opposite side of the ketone substrate, combine in a matched manner to deliver reduction products with very high enantiomeric excess.

Ruthenium-Catalyzed Direct Asymmetric Reductive Amination of Diaryl and Sterically Hindered Ketones with Ammonium Salts and H2

Hu, Le' an,Zhang, Yao,Zhang, Qing-Wen,Yin, Qin,Zhang, Xumu

, p. 5321 - 5325 (2020/02/28)

A Ru-catalyzed direct asymmetric reductive amination of ortho-OH-substituted diaryl and sterically hindered ketones with ammonium salts is reported. This method represents a straightforward route toward the synthesis of synthetically useful chiral primary diarylmethylamines and sterically hindered benzylamines (up to 97 % yield, 93–>99 % ee). Elaborations of the chiral amine products into bioactive compounds and a chiral ligand were demonstrated through manipulation of the removable and convertible -OH group.
