98717-16-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 98717-16-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,7,1 and 7 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 98717-16:
(7*9)+(6*8)+(5*7)+(4*1)+(3*7)+(2*1)+(1*6)=179
179 % 10 = 9
So 98717-16-9 is a valid CAS Registry Number.

Direct Catalytic N-Alkylation of α-Amino Acid Esters and Amides Using Alcohols with High Retention of Stereochemistry

Yan, Tao,Feringa, Ben L.,Barta, Katalin

, p. 2303 - 2307 (2021/05/11)

The direct functionalization of naturally abundant chiral scaffolds such as α-amino acid esters or amides with widely abundant alcohols, without any racemization, is a demanding transformation that is of central importance for the synthesis of bio-active compounds. Herein a robust and general method was developed for the direct N-alkylation of α-amino acid esters and amides with alcohols. This powerful ruthenium-catalyzed methodology is atom-economic, base-free, and allowed for excellent retention of stereochemical integrity. The use of diphenylphosphate as additive was crucial for significantly enhancing reactivity and product selectivity. Notably, the only by-product was water and both substrates could be potentially derived from renewable resources.

A convenient and highly enantioselective synthesis of (S)-2-pipecolic acid: an efficient access to caine anesthetics

Yang, Yuyan,Li, Hua,You, Zhonglin,Zhang, Xingxian

, p. 3084 - 3089 (2021/08/12)

A novel and enantioselective synthesis of (S)-2-pipecolic acid (5) has been achieved from Oppolzer’s sultam (1) and ethyl N-(diphenylmethylene)glycinate (2) as readily available starting materials. The highly stereoselective alkylation of chiral glycine intermediate (3) with 1,4-dibromobutane afforded the key backbone of (S)-2-pipecolic acid (5) in one-step that was utilized into the preparation of the local anesthetics mepivacaine, ropivacaine and bupivacaine.
