Uses

Different sources of media describe the Uses of 94594-90-8 differently. You can refer to the following data:
1. (2R)-Bornane-10,2-sultam is a reagent used to make Camphorsultam conjugates.
2. (1S,2R)-(-)-10,2-Camphorsultam is used in the asymmetric synthesis of (S)- and (R)-N-Fmoc-S-trityl-α-methylcysteine. It is used as proton source in the synthesis of chiral α,γ-substituted γ-butyrolactones. It is also employed as a chiral probe for the optical resolution by HPLC and X-ray crystallographic determination of the absolute stereochemistry of carboxylic acids. Also used to prepare N-acryloyl derivatives which are employed as dienophiles in asymmetric Diels-Alder reactions. and for other asymmetric transformations.
3. (1S)-(?)-2,10-Camphorsultam may be used in the asymmetric synthesis of (S)- and (R)-N-Fmoc-S-trityl-α-methylcysteine. It may be used as proton source in the synthesis of chiral α,γ-substituted γ-butyrolactones.

General Description

(1S,2R,4R)-(?)-2,10-Camphorsultam may be employed as a chiral probe for the optical resolution by HPLC and X-ray crystallographic determination of the absolute stereochemistry of carboxylic acids.

Check Digit Verification of cas no

The CAS Registry Mumber 94594-90-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,4,5,9 and 4 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 94594-90:
(7*9)+(6*4)+(5*5)+(4*9)+(3*4)+(2*9)+(1*0)=178
178 % 10 = 8
So 94594-90-8 is a valid CAS Registry Number.

Palladium-Catalyzed Stereoselective Cyclization of in Situ Formed Allenyl Hemiacetals: Synthesis of Rosuvastatin and Pitavastatin

Spreider, Pierre A.,Breit, Bernhard

supporting information, p. 3286 - 3290 (2018/06/11)

A diastereoselective palladium-catalyzed cyclization of allenyl hemiacetals is described. It permits the selective synthesis of 1,3-dioxane derivatives, precursors for syn-configured 1,3-diols which make an appearance in all of the statin representatives. The reaction allows the total synthesis of Rosuvastatin and Pitavastatin in a straightforward fashion.

Tosvinyl and besvinyl as protecting groups of imides, azinones, nucleosides, sultams, and lactams. Catalytic conjugate additions to tosylacetylene

Petit, Elena,Bosch, Llus,Font, Joan,Mola, Laura,Costa, Anna M.,Vilarrasa, Jaume

, p. 8826 - 8834 (2015/01/08)

The use of the 2-(4-methylphenylsulfonyl)-ethenyl (tosvinyl, Tsv) group for the protection of the NH group of a series of imides, azinones (including AZT), inosines, and cyclic sulfonamides has been examined. The Tsvprotected derivatives are obtained in excellent yields by conjugate addition to tosylacetylene (ethynyl p-tolyl sulfone). The stereochemistry of the double bond can be controlled at will: with only 1 mol % of Et3N or with catalytic amounts of NaH, the Z stereoisomers are generated almost exclusively, while the E isomers are obtained using a stoichiometric amount of DMAP. Analogous phenylsulfonylvinyl-protected groups (with the besvinyl or Bsv group instead of Tsv) are obtained stereospecifically by reaction with (Z)- or (E)-bis(phenylsulfonyl)ethene. For lactams and oxazolidinones, this last method is much better. The Tsv and Bsv groups are stable in the presence of non-nucleophilic bases and to acids. They can be removed highly effectively via a conjugate addition-elimination mechanism using pyrrolidine or sodium dodecanethiolate as nucleophiles.

A facile, inexpensive and scalable route to thiol-protected α-methyl cysteine

Johnston, Heather J.,Hulme, Alison N.

supporting information, p. 591 - 594 (2013/04/10)

A facile, scalable synthesis of α-methyl cysteine with three alternate thiol protecting groups (trityl, allyl and tert-butyl) is described. The thiol-protected amino acids are obtained in six steps from l-cysteine ethyl ester and are ideally suited for a range of natural product and solid-phase peptide synthesis applications.
