3-diaryl indenone epoxide (DIO) and mesoionic oxidopyrylium ylide (PY) is governed by dual-λ gating, in which PY can undergo fast [5+2] cycloaddition with BCN. A photoswitchable strategy for photoclick labeling with spatiotemporal control was developed, recycling the unreacted PY to minimize side-effects. Also, molecular diffusion of the reactive PY was compensated for by improvement of the spatial accuracy
2,3-二芳基茚酮环氧化物 (DIO) 和中离子氧化吡啶叶立德 (PY) 之间的光开关平衡由双 λ 门控控制,其中 PY 可以与 BCN 进行快速 [5+2] 环加成。开发了一种用于时空控制的光点击标记的光切换策略,回收未反应的 PY 以最大限度地减少副作用。此外,通过提高空间精度来补偿反应性 PY 的分子扩散。
