Journal ArticleDOI
The atom economy--a search for synthetic efficiency
TL;DR: Transition metal-catalyzed methods that are both selective and economical for formation of cyclic structures, of great interest for biological purposes, represent an important starting point for this long-term goal.

Rh(III)-catalyzed C–H activation/[4 + 3] cycloaddition of benzamides and vinylcarbenoids: facile synthesis of azepinones
TL;DR: In this paper, a kinetic isotope effect study was conducted and a plausible mechanism was proposed for cycloaddition with benzamides to access azepinones, which makes a feature of simple starting materials, mild reaction conditions and high efficiency.

Gold-Catalyzed [4C+2C] Cycloadditions of Allenedienes, including an Enantioselective Version with New Phosphoramidite-Based Catalysts: Mechanistic Aspects of the Divergence between [4C+3C] and [4C+2C] Pathways

TL;DR: Experimental and theoretical data dismiss a cationic mechanism involving intermediate II and suggest that the formation of the [4C+2C] cycloadducts might arise from a 1,2-alkyl migration (ring contraction) in a cycloheptenyl Au-carbene intermediate (IV), itself arising from a [ 4C+3C] concerted cycloaddition of the allenediene.
