Herein, we disclose a highly regio-/chemoselective tandem asymmetric dearomatized halofunctionalization reaction of phenoltethered ynamides with diverse electrophilic halogenation sources in a catalyst-free manner for the practical and rapid assembly of a series of halogenated spirocyclic enones. Besides, the related dearomatized selenation and protonation are also achieved,affording the corresponding selenated and protonated spirocycles in high efficiency. Moreover, the enantioselectivities of these products can be perfectly induced by Evans auxiliaries (99%ees). Significantly, this protocol not only represents the first tandem asymmetric halofunctionalization reaction of phenol derivatives, but also constitutes the first asymmetric halogenation/selenation of ynamides. Theoretical calculations indicate a remote induction model of Evans chiral auxiliary-attached keteniminium.

We proposed a hybrid imaging scheme to estimate a high-resolution absolute depth map from low photon counts. It leverages measurements of photon arrival times from a single-photon LiDAR and an intensity image from a conventional high-resolution camera. Using a tailored fusion algorithm, we jointly processed the raw measurements from both sensors and output a high-resolution absolute depth map. We scaled up the resolution by a factor of 10, achieving 1300 × 2611 pixels and extending ~4.7 times the unambiguous range. These results demonstrated the superior capability of long-range high-resolution 3D imaging without range ambiguity.
