Cycloadditions of cyclohexynes and cyclopentyne. [PDF]
Journal of the American Chemical Society, 2014 We report the strategic use of cyclohexyne and the more elusive intermediate, cyclopentyne, as a tool for the synthesis of new heterocyclic compounds. Experimental and computational studies of a 3-substituted cyclohexyne are also described.

Photochemical intermolecular dearomative cycloaddition of bicyclic azaarenes with alkenes
Science, 2021 Heteroaromatics lured into cycloadditions The Diels-Alder reaction is widely used to produce six-membered carbon rings from alkenes and dienes. Heteroaromatics such as quinolines resemble dienes in principle, but in practice their pairs of double bonds ...

The Huisgen Reaction: Milestones of the 1,3‐Dipolar Cycloaddition
Angewandte Chemie, 2020 The concept of 1,3‐dipolar cycloadditions was presented by Rolf Huisgen 60 years ago. Previously unknown reactive intermediates, for example azomethine ylides, were introduced to organic chemistry and the (3+2) cycloadditions of 1,3‐dipoles to multiple ...
