Recent developments in glycosyl urea synthesis

The area of sugar urea derivatives has received considerable attention in recent years because of the unique structural properties and activities that these compounds display. The urea-linkage at the anomeric center is a robust alternative to the naturally occurring O- and N-glycosidic linkages of oligosaccharides and glycoconjugates, and the natural products that have been identified to contain these structures show remarkable biological activity. While methods for installing the beta-urea-linkage at the anomeric center have been around for decades, the first synthesis of alpha-urea glycosides has been much more recent. In either case, the selective synthesis of glycosyl ureas can be quite challenging, and a mixture of alpha- and -isomers will often result. This paper will provide a comprehensive review of the synthetic approaches to alpha- and -urea glycosides and examine the structure and activity of the natural products and their analogues that have been identified to contain them.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 1192-07-0, help many people in the next few years.Formula: C3H5NO2

Stereoselective synthesis of a monocyclic peloruside A analogue

Chemical Equation Presentation The stereoselective synthesis of the monocyclic peloruside A analogue 4 has been achieved, following a new efficient approach for the introduction of the side chain, involving a late-stage addition of vinyl lithium species 7a to aldehyde 8. Further key steps are a highly diastereoselective allyltitanation reaction and a RCM-based macrocyclization.

Synthesis of the enantiomers of the dual function 2-nitroimidazole radiation sensitizer RB 6145

Short, efficient pathways are described for the synthesis of racemic 2-nitroimidazole radiation sensitizer RB-6145 (2a) and each of its corresponding (R)- and (S)-enantiomers (2b and 2c, respectively). The synthesis of each enantiomer commences with the appropriate chiral epichlorohydrin and utilizes a novel application of 3-trimethylsilyl-2-oxazolidinone (3b) as a mild, safe surrogate for highly toxic aziridine. The synthesis of the (R)-enantiomer (2b) has been successfully scaled up to provide multi-kilo quantities of material for early stage preclinical evaluation.

Total synthesis of elisabethin A: Intramolecular Diels-Alder reaction under biomimetic conditions

We describe the first total synthesis of the marine diterpenoid elisabethin A. The synthesis uses (S)-hydroxy-2-methyl-propionate as the chiral starting material, which is elaborated into a dienyl-iodide and added to an aryl acetic acid ester via enolate alkylation. The hydroquinoid system is oxidized to the quinone which serves as the dienophile in a highly stereocontrolled intramolecular Diels-Alder addition. This IMDA reaction, which to our knowledge is the first one to employ a terminal (Z)-diene, proceeds under biomimetic conditions (water, ferrichloride as the oxidant, room temperature) with high yield and stereoselectivity. The Diels-Alder adduct is transformed into the natural product via a three-step sequence including selective hydrogenation, base-catalyzed epimerization of the cis- into the trans-decalin system and O-demethylation.

Addition to activated imines of enolates from chiral N-acyloxazolidinones

The lithium and titanium enolates of N-acyloxazolidinones 1a-c add in their chelated forms to PhCH=NTs, to give stereoselectively the beta-amino acid derivatives 3a-c and 4a-c. The relative configurations of the newly created chiral centres were established by conversion to the trans (8a-c) or cis (9a, c) beta-lactams. Absolute stereochemistry was assigned by correlation with known compounds 10a and ent-11a, together with an X-ray crystal structure determination on 9a. The use of the lithium enolate of 1a at -78C gave only a 1.4:1 ratio of anti product 3a to syn product 4a, but this ratio was improved to >5:1 by the use of the chlorotitanium enolate of 1a at-55C or below. Similar results were obtained by using the chlorotitanium enolate of 1b, but for the chlorotitanium enolate of the N-(phenylacetyl)oxazolidinone 1c the proportion of syn product 4c to anti product was significantly greater, consistent with a kinetically controlled reaction involving the si face of the chelated (Z)-enolate and the competing alternative transition states TS3 (reaction on si face of imine) and TS7 (reaction on re face of imine).

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Product Details of 16251-45-9, you can also check out more blogs about16251-45-9
