60168-64-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 60168-64-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,0,1,6 and 8 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 60168-64:
(7*6)+(6*0)+(5*1)+(4*6)+(3*8)+(2*6)+(1*4)=111
111 % 10 = 1
So 60168-64-1 is a valid CAS Registry Number.

Regioselective mono and multiple alkylation of diols and polyols catalyzed by organotin and its applications on the synthesis of value-added carbohydrate intermediates

Xu, Hengfu,Ren, Bo,Zhao, Wei,Xin, Xiaoting,Lu, Yuchao,Pei, Yuxin,Dong, Hai,Pei, Zhichao

, p. 3490 - 3499 (2016/06/06)

A catalytic amount of dibutyltin dichloride was used to develop regioselective alkylation of diols and multiple alkylation of polyols. Alkyl groups, including allyl, alkynyl and long-chain alkyl groups, were successfully introduced to one or two hydroxyl

Synthesis of oxacyclic scaffolds via dual ruthenium hydride/Bronsted acid-catalyzed isomerization/cyclization of allylic ethers

Ascic, Erhad,Ohm, Ragnhild G.,Petersen, Rico,Hansen, Mette R.,Hansen, Casper L.,Madsen, Daniel,Tanner, David,Nielsen, Thomas E.

supporting information, p. 3297 - 3300 (2014/04/03)

A ruthenium hydride/Bronsted acid-catalyzed tandem sequence is reported for the synthesis of 1,3,4,9-tetrahydropyrano[3,4-b]indoles (THPIs) and related oxacyclic scaffolds. The process was designed on the premise that readily available allylic ethers would undergo sequential isomerization, first to enol ethers (Ru catalysis), then to oxocarbenium ions (Bronsted acid catalysis) amenable to endo cyclization with tethered nucleophiles. This methodology provides not only an attractive alternative to the traditional oxa-Pictet-Spengler reaction for the synthesis of THPIs, but also convenient access to THPI congeners and other important oxacycles such as acetals.

Hydrophobic amplification of noncovalent organocatalysis

Kleiner, Christian M.,Schreiner, Peter R.

, p. 4315 - 4317 (2007/10/03)

The effects of hydrogen-bonding organocatalysts and water for the acceleration of epoxide openings with a variety of nucleophiles are additive and lead to excellent yields of the catalyzed reactions in water. The Royal Society of Chemistry 2006.
