252681-06-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 252681-06-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,2,6,8 and 1 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 252681-06:
(8*2)+(7*5)+(6*2)+(5*6)+(4*8)+(3*1)+(2*0)+(1*6)=134
134 % 10 = 4
So 252681-06-4 is a valid CAS Registry Number.

Rhodium-catalyzed Reformatsky-type reaction for asymmetric synthesis of difluoro-β-lactams using menthyl group as a chiral auxiliary

Tarui, Atsushi,Ozaki, Daiki,Nakajima, Naoko,Yokota, Yuto,Sokeirik, Yasser S.,Sato, Kazuyuki,Omote, Masaaki,Kumadaki, Itsumaro,Ando, Akira

, p. 3839 - 3843 (2008/09/21)

We developed a new methodology for the asymmetric Reformatsky-type reaction of (-)-menthyl bromodifluoroacetate (2) with imine in the presence of RhCl(PPh3)3. Ester 2 with the cost-effective chiral auxiliary gave (S)-difluoro-β-lacta

Enantioselective synthesis of α,α-difluoro-β-amino acid and 3,3- difluoroazetidin-2-one via the reformatsky-type reaction of ethyl bromodifluoroacetate with chiral 1,3-oxazolidines

Marcotte, Stephane,Pannecoucke, Xavier,Feasson, Christian,Quirion, Jean-Charles

, p. 8461 - 8464 (2007/10/03)

Chiral oxazolidines 2a-e can be diastereoselectively alkylated with BrCF2CO2Et to furnish 3,3-difluoroazetidin-2-ones 3a-e with up to 99% de. Selective cleavage of the chiral appendage provided the corresponding unsubstituted azetidinones. Formation of optically pure α,α-difluoro-β- amino acids 5a-c can be achieved by acidic hydrolysis of N-vinyl-azetidin-2- ones.
