176107-53-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 176107-53-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,6,1,0 and 7 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 176107-53:
(8*1)+(7*7)+(6*6)+(5*1)+(4*0)+(3*7)+(2*5)+(1*3)=132
132 % 10 = 2
So 176107-53-2 is a valid CAS Registry Number.

Ynamide Carbopalladation: A Flexible Route to Mono-, Bi- and Tricyclic Azacycles

Campbell, Craig D.,Greenaway, Rebecca L.,Holton, Oliver T.,Walker, P. Ross,Chapman, Helen A.,Russell, C. Adam,Carr, Greg,Thomson, Amber L.,Anderson, Edward A.

, p. 12627 - 12639 (2015/09/01)

Bromoenynamides represent precursors to a diversity of azacycles by a cascade sequence of carbopalladation followed by cross-coupling/electrocyclization, or reduction processes. Full details of our investigations into intramolecular ynamide carbopalladation are disclosed, which include the first examples of carbopalladation/cross-coupling reactions using potassium organotrifluoroborate salts; and an understanding of factors influencing the success of these processes, including ring size, and the nature of the coupling partner. Additional mechanistic observations are reported, such as the isolation of triene intermediates for electrocyclization. A variety of hetero-Diels-Alder reactions using the product heterocycles are also described, which provide insight into Diels-Alder regioselectivity.

Reductive cyclization of bromoenynamides with alcohols as hydride source: Synthesis and reactions of 2-amidodienes

Greenaway, Rebecca L.,Campbell, Craig D.,Chapman, Helen A.,Anderson, Edward A.

, p. 3187 - 3194 (2013/01/15)

Under basic conditions in alcoholic solvents, bromoenynamides undergo palladium-catalyzed cyclization to cyclic 2-amidodienes in good to excellent yields. This process represents the first use of an alcohol as a hydride source in an alkyne carbopalladation/termination sequence, with the site selectivity of the reduction showing a strong dependence on the tethering ring size (5-8), and the nature of the alcohol and base. Reaction of the dienes with a range of dienophiles (including alkenes, alkynes and arynes) under various conditions gives bi- and tricyclic azacycles, which can be further oxidized to the aromatic azacycles.

Thermal removal of BOC-protecting groups during preparation of open-chain polyamines

Krakowiak, Krzysztof E.,Bradshaw, Jerald S.

, p. 3999 - 4004 (2007/10/03)

Per-N-tosylated 3,8-diaza-1,10-decanediamine (9), 4,9-diaza-1,12-dodecanediamine (spermine) (10) and 3,6,9,14,17,20-hexaaza-1,22-docosanediamine (11) were prepared by treating mono-BOC-protected, per-N-tosylated 1,2-ethanediamine (5), 1,3-propanediamine (6) and triethylenetetraamine (7), respectively, with 1,4-dibromobutane and removing the BOC-protecting groups at 100-120°C.
