(2R,3R)-2-(4-Methoxy-phenyl)-3-methyl-cyclopropanecarboxylic acid ethyl ester is a complex organic compound with the molecular formula C14H18O3. It is a chiral molecule, meaning it has a non-superimposable mirror image, and the specific configuration is indicated by the (2R,3R) notation. (2R,3R)-2-(4-Methoxy-phenyl)-3-methyl-cyclopropanecarboxylic acid ethyl ester features a cyclopropane ring, which is a three-carbon ring, with a methyl group at position 3 and a 4-methoxyphenyl group at position 2. The carboxylic acid group is esterified with an ethyl group, making it an ethyl ester. This chemical structure is significant in organic chemistry and may have applications in the synthesis of pharmaceuticals or other specialty chemicals due to its unique stereochemistry and functional groups.

Check Digit Verification of cas no

The CAS Registry Mumber 59203-23-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,9,2,0 and 3 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 59203-23:
(7*5)+(6*9)+(5*2)+(4*0)+(3*3)+(2*2)+(1*3)=115
115 % 10 = 5
So 59203-23-5 is a valid CAS Registry Number.

A transition-metal-free & diazo-free styrene cyclopropanation

Herraiz, Ana G.,Suero, Marcos G.

, p. 9374 - 9379 (2019)

An operationally simple and broadly applicable novel cyclopropanation of styrenes using gem-diiodomethyl carbonyl reagents has been developed. Visible-light triggered the photoinduced generation of iodomethyl carbonyl radicals, able to cyclopropanate a wide array of styrenes with excellent chemoselectivity and functional group tolerance. To highlight the utility of our photocyclopropanation, we demonstrated the late-stage functionalization of biomolecule derivatives.
