Abstract
Amine-targeting reactions that work under biocompatible conditions or in water are green processes that are extremely useful for the synthesis of functional materials and biotherapeutics. Unfortunately, despite the usefulness of this reaction, there are very few good amine-specific click methods reported thus far. Here, we report an amine-specific click reagent using alkynone β-trifluoroborates as the electrophiles. These boron-containing alkynyl reagents exhibit extremely high chemoselectivity toward amines even in the presence of thiols. The resulting oxaboracycle products are bench-stable, displaying the reactivities of both organoborates and enaminones. Intrinsic advantages of this methodology include benign reaction conditions, operational simplicity, remarkable product stability, and excellent chemoselectivity, which satisfy the criteria of click chemistry and demonstrate the high potential in bioconjugation. Hence, this water-based chemical approach is also applicable to the modification of native amino acids, peptides, and proteins. Ultimately, the essential role of water during the reaction was elucidated.

Abstract
![]()
A dual catalyst system
based on ligand exchange of two diphosphine
ligands possessing different properties in a copper complex has been
devised to merge metal- and photocatalytic activation modes. This
strategy has been applied to the formal anti-hydroboration of activated
internal alkynes via a tandem sequence in which Cu/Xantphos catalyzes
the B2pin2-syn-hydroboration
of the alkyne whereas Cu/BINAP serves as a photocatalyst for visible
light-mediated isomerization of the resulting alkenyl boronic ester.
Photochemical studies by means of UV–vis absorption, steady-state
and time-resolved fluorescence, and transient absorption spectroscopy
have allowed characterizing the photoactive Cu/BINAP species in the
isomerization reaction and its interaction with the intermediate syn-alkenyl boronic ester through energy transfer from the
triplet excited state of the copper catalyst. In addition, mechanistic
studies shed light into catalyst speciation and the interplay between
the two catalytic cycles as critical success factors.
