Check Digit Verification of cas no

The CAS Registry Mumber 33099-08-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,3,0,9 and 9 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 33099-08:
(7*3)+(6*3)+(5*0)+(4*9)+(3*9)+(2*0)+(1*8)=110
110 % 10 = 0
So 33099-08-0 is a valid CAS Registry Number.

Synthesis of dysideaproline e using organocatalysis

Owusu-Ansah, Ernest,Durow, Amanda C.,Harding, John R.,Jordan, Angela C.,O'Connell, Susan J.,Willis, Christine L.

body text, p. 265 - 272 (2011/02/24)

(S)-4,4-Dichloro-3-methylbutanoic acid was prepared in 51% overall yield from commercially available starting materials using an organocatalytic transfer hydrogenation to 4,4-dichloro-3-methylbut-2-enal in the key step. The (S)-dichloro acid was used as an intermediate in the first total synthesis of dysideaproline E and a diastereomer confirming the structure of the natural product.

Total synthesis of the chlorinated marine natural product dysamide B

Durow, Amanda C.,Long, G. Cliona,O'Connell, Susan J.,Willis, Christine L.

, p. 5401 - 5404 (2007/10/03)

Two approaches to the synthesis of (2S,4S)-5,5-dichloroleucine are compared, and the parent amino acid was used in the first total synthesis of the polychlorinaled marine natural product, dysamide B. A key step was the lead tetraacetate-mediated decarboxylation of an α,α-dichloro acid in the presence of 1,4-cyclohexadiene to generate the dichloromethyl group.

Effective methods for the synthesis of N-methyl β-amino acids from all twenty common α-amino acids using 1,3-oxazolidin-5-ones and 1,3-oxazinan-6-ones

Hughes, Andrew B.,Sleebs, Brad E.

, p. 2611 - 2637 (2007/10/03)

N-Methyl β-amino acids are generally required for application in the synthesis of potentially bioactive modified peptides and other oligomers. Previous work highlighted the reductive cleavage of 1,3-oxazolidin-5-ones to synthesise N-methyl α-amino acids. Starting from α-amino acids, two approaches were used to prepare the corresponding N-methyl β-amino acids. First, α-amino acids were converted to N-methyl α-amino acids by the so-called '1,3-oxazolidin-5-one strategy', and these were then homologated by the Arndt-Eistert procedure to afford N-protected N-methyl β-amino acids derived from the 20 common α-amino acids. These compounds were prepared in yields of 23-57% (relative to N-methyl α-amino acid). In a second approach, twelve N-protected α-amino acids could be directly homologated by the Arndt-Eistert procedure, and the resulting β-amino acids were converted to the 1,3-oxazinan-6-ones in 30-45% yield. Finally, reductive cleavage afforded the desired N-methyl β-amino acids in 41-63% yield. One sterically congested β-amino acid, 3-methyl-3-aminobutanoic acid, did give a high yield (95%) of the 1,3-oxazinan-6-one (65), and subsequent reductive cleavage gave the corresponding AIBN-derived N-methyl β-amino acid 61 in 71% yield (Scheme 2). Thus, our protocols allow the ready preparation of all N-methyl β-amino acids derived from the 20 proteinogenic α-amino acids.
