229 results about "Cyclopropene" patented technology

Cyclopropene is an organic compound with the formula C₃H₄. It is the simplest cycloalkene. Because the ring is highly strained, cyclopropene is difficult to prepare and highly reactive. This colorless gas has been the subject for many fundamental studies of bonding and reactivity. It does not occur naturally, but derivatives are known in some fatty acids. Derivatives of cyclopropene are used commercially to control ripening of some fruit.

Tetrazine-based bio-orthogonal coupling reagents and methods

Coupling reactions, suitable for use in organic or aqueous media, are performed by contacting a 1,2,4,5-tetrazine with a dienophile. The dienophile may be covalently bonded to a protein, and the coupling reaction may be performed in biological media such as those containing cells or cell lysates. The reactions may be performed in the presence of primary amines, thiols, acetylenes, azides, phosphines, and products of Staudinger and / or Sharpless-Huisgen reactions Novel 3-substituted cyclopropene compounds and trans-cyclooctenes are exemplary dienophiles for these reactions.
