Three-and four-membered rings, widespread motifs in nature and medicinal chemistry, have
fascinated chemists ever since their discovery. However, due to energetic considerations …

The copper-catalyzed functionalization of enyne derivatives has recently emerged as a
powerful approach in contemporary synthesis. Enynes are versatile and readily accessible …

Asymmetric catalysis holds a prominent position among the important developments in
chemistry during the 20th century. This was acknowledged by the 2001 Nobel Prize in …

Herein, we have developed metal and oxidant-free visible light-promoted alkene vs. alkyne
regio-and chemoselective radical cascade cyclization of electronically unbiased 1, 6-enynes …

Dirhodiums, which feature lantern-or paddlewheel-like structures, have emerged as a class
of useful catalysts in organic synthesis. Among the transformations catalyzed by dirhodiums …

Two intermolecular hydroalkenylation reactions of 1, 6-enynes are presented which yield
substituted 5-membered carbo-and-heterocycles. This reactivity is enabled by a cationic bis …

Disclosed here is the first geminal (gem‐) hydroborative cyclization of enynes. Different from
known hydroborative cyclizations, this process adds hydrogen and boron to the same …

We developed time‐atom economic regio‐and chemoselective sulfonyl radical triggered 5‐
exo‐dig cyclization of unactivated 1, 6‐enynes with sulfonyl halides under metal, additive …

Transition-metal catalyzed asymmetric cyclization of 1, 6-enynes has emerged as a powerful
method for the construction of carbocycles and heterocycles. However, very rare examples …

Previously, we developed a gold-catalyzed cycloisomerization of dienediynes to synthesize
the fused 6, 7, 5-tricyclic compounds. This reaction involves aliphatic C–H functionalization …
