Cyclic alkynes (e.g., cyclooctynes such as dibenzocyclooctynes) can be photochemically generated from cyclopropenones as disclosed herein. The cyclic alkynes can be reacted (e.g., in situ) with materials having alkyne-reactive groups (e.g., azide groups in a “click” reaction). In preferred embodiments, the generation and reaction of the cyclic alkyne can proceed in the absence of a catalyst (e.g., Cu(I)). These reactions can be useful, for example, for the selective labeling of living cells that are metabolically modified with azido-containing surface monosaccharides, or for light-directed surface patterning.
环状炔烃(例如,二苯并环辛烯等)可以从环丙酮烯光化学地生成,如本文所披露的。这些环状炔烃可以与具有炔烃反应基团(例如,“点击”反应中的偶氮基团)的材料发生反应(例如,在原位)。在优选实施例中,环状炔烃的生成和反应可以在无催化剂(例如,Cu(I))的情况下进行。这些反应可以用于例如,用于选择性标记通过含有偶氮基团表面单糖代谢修饰的活细胞,或用于光导向表面图案。
