16691-59-1 Usage

Uses

Useful synthetic building block demonstrated by Tristan Lambert to enable access to chiral Br?nsted acid catalysts.

Check Digit Verification of cas no

The CAS Registry Mumber 16691-59-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,6,9 and 1 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 16691-59:
(7*1)+(6*6)+(5*6)+(4*9)+(3*1)+(2*5)+(1*9)=131
131 % 10 = 1
So 16691-59-1 is a valid CAS Registry Number.

Highly Enantioselective Synthesis of Cyclic Aminals with a Cyclopentadiene-Based Chiral Carboxylic Acid

Sui, Yuebo,Cui, Peng,Liu, Sensheng,Zhou, Yanmei,Du, Peng,Zhou, Haifeng

supporting information, p. 215 - 218 (2018/01/26)

A highly enantioselective aminalization of 2-aminobenzenesulfonamides and aldehydes catalyzed by a novel cyclopentadiene-based chiral carboxylic acid has been realized. The cost-effective and readily synthesized cyclopentadiene-based chiral carboxylic aci

Thermal Rearrangements and Reactions of 5-Alkyl-1,2,3,4,5-pentakis(methoxycarbonyl)cyclopentadienes

Jefferson, Elizabeth A.,Warkentin, John

, p. 463 - 467 (2007/10/02)

Studies of the thermal reactions of five 5-alkyl-1,2,3,4,5-pentakis(methoxycarbonyl)cyclopentadienes in methanol solvent are described, where the alkyl groups are benzhydryl, methoxymethyl, 1-adamantyl, p-methoxybenzyl, and benzyl.The benzyl cyclopentadiene system undergoes thermal -sigmatropic rearrangement via methoxycarbonyl migrations while the other cyclopentadienes undergo C-alkyl bond heterolysis to ion-pair intermediates, which are scavenged by solvent.First-order rate constants for solvolysis of the methoxymethyl, 1-adamantyl, and p-methoxymethyl systems in methanol solvent were determined and that for the benzhydryl system was estimated from a single measurement of the half-life.
