221635-90-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 221635-90-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,1,6,3 and 5 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 221635-90:
(8*2)+(7*2)+(6*1)+(5*6)+(4*3)+(3*5)+(2*9)+(1*0)=111
111 % 10 = 1
So 221635-90-1 is a valid CAS Registry Number.

The synthesis of 4-triflyloxy-2,6,6-trimethyl-2,4-cyclohexadienone (13), bicyclo[2.2.2]octenones 1a-j and 15a-j, and bicyclo[2.2.2]octadienones 2a-f, 6a-d, and 11a-f is described. The 2,4-cyclohexadienones 4 and 13 were used for the first time as nondimer

Pd-Catalyzed Carbonylation of Vinyl Triflates to Afford α,β-Unsaturated Aldehydes, Esters, and Amides under Mild Conditions

Zhang, Shaoke,Neumann, Helfried,Beller, Matthias

supporting information, p. 3528 - 3532 (2019/05/24)

An efficient and general protocol for the synthesis of α,β-unsaturated aldehydes, esters, and amides via carbonylation of vinyl triflates including derivatives of camphor, ketoisophorone, verbenone, and pulegone was developed. Crucial for these transformations is the use of a specific palladium catalyst containing a pyridyl-substituted dtbpx-type ligand. This procedure also allows for an easy access of dicarbonylated products from the corresponding ketones.

Value of zeolites in asymmetric induction during photocyclization of pyridones, cyclohexadienones and naphthalenones

Sivasubramanian, Karthikeyan,Kaanumalle, Lakshmi S.,Uppili, Sundararajan,Ramamurthy

, p. 1569 - 1576 (2008/02/05)

Two strategies, namely chiral inductor and chiral auxiliary approaches, have been examined within zeolites with the aim of achieving asymmetric induction during the photocyclization of cyclohexadienone, naphthalenone and pyridone derivatives. Within zeoli
