74104-57-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 74104-57-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,1,0 and 4 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 74104-57:
(7*7)+(6*4)+(5*1)+(4*0)+(3*4)+(2*5)+(1*7)=107
107 % 10 = 7
So 74104-57-7 is a valid CAS Registry Number.

Stereoselective Yang cyclizations of α-amido ketones

Griesbeck, Axel G.,Heckroth, Heike,Lex, Johann

, p. 1109 - 1110 (1999)

The photocyclization of methyl-substituted α-acetamido butyrophenone derivatives is highly stereoselective and leads to 2-aminocyclobutanols with complete control of three new stereogenic centers.

Catalytic transformation of esters of 1,2-azido alcohols into α-amido ketones

Kim, Yongjin,Pak, Han Kyu,Rhee, Young Ho,Park, Jaiwook

supporting information, p. 6549 - 6552 (2016/06/01)

The esters of 1,2-azido alcohols were transformed into α-amido ketones without external oxidants through the Ru-catalyzed formation of N-H imines with the liberation of N2 followed by intramolecular migration of the acyl moiety. A wide range of α-amido ketones were obtained, and one-pot transformation into the corresponding oxazoles (or a thiazole) was demonstrated.

α-Carbonyl substituent effect on the lifetimes of triplet 1,4-biradicals from norrish-type-II reactions

Cai, Xichen,Cygon, Peter,Goldfuss, Bernd,Griesbeck, Axel G.,Heckroth, Heike,Fujitsuka, Mamoru,Majima, Tetsuro

, p. 4662 - 4667 (2008/03/13)

Triplet 1,4-biradicals were generated by Norrish-Type-II hydrogen transfer from cx-heteroatom-substituted -branched butyrophenones 1-6 and detected by laser flash absorption measurements. For three oxy-substituted compounds 2-4 (Rα = OH, OCOMe,
