WebMar 31, 2014 · In conjunction with a new class of cyclooctyne d -amino acids, the NIR probes were used to image bacterial peptidoglycan (PG) without the need for cytotoxic copper catalyst or washing away excess probe. This platform should facilitate the in vivo imaging of PG in pathogenic bacteria with bioorthogonal chemistry. Abstract Cyclooctyne (C 8 H 12) is the smallest cycloalkyne capable of being isolated and stored as a stable compound. Despite this, smaller cycloalkynes can be produced and trapped through reactions with other organic molecules or through complexation to transition metals. See more In organic chemistry, a cycloalkyne is the cyclic analog of an alkyne (−C≡C−). A cycloalkyne consists of a closed ring of carbon atoms containing one or more triple bonds. Cycloalkynes have a general formula CnH2n−4. … See more Initial efforts toward the synthesis of strained cycloalkynes showed that cycloalkynes could be generated via the elimination of hydrochloric acid from 1-chloro-cycloalkene … See more Strained cycloalkynes are able to undergo all addition reactions typical to open chain alkynes. Due to the activated nature of the cyclic carbon–carbon triple bond, many alkyne addition … See more Due to the significant geometric constraints imposed by the R−C≡C−R functionality, cycloalkynes smaller than cyclodecyne (C10H16) result in highly strained structures. … See more Angle strain in cycloalkynes arises from the deformation of the R−C≡C bond angle which must occur in order to accommodate the molecular geometry of rings containing less than ten carbons. The strain energies associated with cyclononyne … See more
