oxazolidine การใช้

• "' Thiazolidine "'is a heterocyclic organic compound with a 5-membered analog of oxazolidine.
• The choice of linker between the two oxazolidine rings has a large impact on the performance when used to cure isocyanates.
• Cyclization of an azomethine ylide with a carbonyl affords a spirocyclic oxazolidine, which loses CO 2 to form a 7-membered ring.
• An "'oxazolidine "'is a five-membered ring compound consisting of three carbons, a nitrogen, and an oxygen.
• In oxazolidine derivatives, there is always a carbon between the oxygen and the nitrogen ( or it would be an " isoxazolidine " ).
• "' Goitrin "'is a sulfur-containing oxazolidine, a cyclic thiocarbamate, that reduces the production of thyroid hormones such as thyroxine.
• Zyvox is a member of an new family of medications, the oxazolidine class; it works by blocking the formation of proteins that enable bacteria to spread inside the body.
• Upon tissue disruption glucosinolates are enzymatically degraded by myrosinase and may yield a variety of biologically active products such as isothiocyanates, thiocyanates, nitriles and oxazolidine-2-thiones.
• A new series of semi-synthetic C-16-spiro-oxazolidine-1, 3-diones prepared from 17-deacetyl vinblastine showed good anti-tubulin activity and lower cytotoxicity.
• As a further demonstration of reactivity one study explored the properties of an ?-formyl aziridine which was found to dimerize as an oxazolidine on formation from the corresponding ester by organic reduction with DIBAL:
• The coupling of amino acid derivatives to a growing peptide chain containing N-terminal pseudoproline generally results in low yields because of the sterically hindered nature of the oxazolidine ( thiazolidine ) ring system and the decreased nucleophilicity of the nitrogen atom.
• The routine use of pseudoproline ( oxazolidine ) dipeptides in the FMOC solid phase peptide synthesis ( SPPS ) of serine-and threonine-containing peptides leads to remarkable improvements in quality and yield of crude products and helps avoid unnecessary repeat synthesis of failed sequences.
• Two conceptually different approaches are feasible for preparing oxazolidine-and thiazolidine-ring-containing dipeptide derivatives : ( 1 ) the in situ acylation of Ser-or Thr-derived oxazolidines or Cys-derived thiazolidines using acid fluorides or N-carboxyanhydrides ( NCA ); and ( 2 ) the direct insertion of the oxazolidine systems into dipeptides ( post-insertion ) containing C-terminal Ser or Thr.
