573692-80-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 573692-80-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,7,3,6,9 and 2 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 573692-80:
(8*5)+(7*7)+(6*3)+(5*6)+(4*9)+(3*2)+(2*8)+(1*0)=195
195 % 10 = 5
So 573692-80-5 is a valid CAS Registry Number.

Rhodium(II)-catalyzed enantioselective synthesis of troponoids

Murarka, Sandip,Jia, Zhi-Jun,Merten, Christian,Daniliuc, Constantin-G.,Antonchick, Andrey P.,Waldmann, Herbert

, p. 7653 - 7656 (2015)

We report a rhodium(II)-catalyzed highly enantioselective 1,3-dipolar cycloaddition reaction between the carbonyl moiety of tropone and carbonyl ylides to afford troponoids in good to high yields with excellent enantioselectivity. We demonstrate that α-diazoketone-derived carbonyl ylides, in contrast to carbonyl ylides derived from diazodiketoesters, undergo [6+3] cycloaddition reactions with tropone to yield the corresponding bridged heterocycles with excellent stereoselectivity. Decisive dipoles: In the rhodium(II)-catalyzed asymmetric 1,3-dipolar cycloaddition of tropone with carbonyl ylides, a programmable chemoselective reaction with the keto group or the 6 π system of tropone was controlled by the substrate (see scheme). The developed method enables the synthesis of complex products in highly enantiomerically enriched form.
