The synthesis of rare macrocyclic alkynediyl sulfides by a Cu-catalyzed Csp -S cross-coupling is presented. The catalytic protocol (Cu(MeCN)4 PF6 /dtbbpy) promotes macrocyclization of peptides, dipeptides and tripeptides at ambient temperature (14 ex

Copper-catalyzed cross-coupling of thiols and bromoalkynes affords a mild, rapid, and selective Csp-S coupling with broad scope, enabling the use of aryl-, alkyl-, and silyl-substituted alkynyl coupling partners (38 total examples, 50-99% yields). Im

The relative stability and predictable reactivity of alkynyl sulfides make them ideal synthons for the development of new transformations. Classic methods for forming alkynyl sulfides relied on dehydrohalogenation approaches. However more recent meth

A library of 50 copper-based complexes derived from bisphosphines and diamines was prepared and evaluated in three mechanistically distinct photocatalytic reactions. In all cases, a copper-based catalyst was identified to afford high yields, where ne

A photochemical dual-catalytic cross-coupling to form alkynyl sulfides via C(sp)−S bond formation is described. The cross-coupling of thiols and bromoalkynes is promoted by a soluble organic carbazole-based photocatalyst using continuous flow techn

A macrocyclic Cu-catalyzed Sonogashira-type cross-coupling reaction has been developed that employs an operationally simple CuCl/phen/Cs2CO3 catalyst system. Macrocyclizations can be performed at relatively high concentrations without the need for sl

The continuous-flow synthesis of a series of 11- to 26-membered macrocycles via copper-catalyzed azide-alkyne cycloaddition is reported. The approach employs homogeneous catalysis to promote formation of triazole-containing macrocycles in good to exc
