Herein we detail a practical synthesis of bullvalene and a variety of mono‐and disubstituted
analogues through cobalt‐catalysed [6+ 2] cycloaddition of cyclooctatetraene to alkynes …

Boronate ester bullvalenes are now accessible in two to four operationally simple steps. This
unlocks late-stage diversification through Suzuki cross-coupling reactions to give mono-, di …

The [6π+ 2π]-cycloaddition of alkynes to 1-methyl-, propyl-, benzyl-, and hydroxymethyl-
substituted 1, 3, 5-cycloheptatrienes in the presence of catalytic systems Ti (acac) 2Cl2 …

Catalytic [6π+ 2π]-cycloaddition of N-carbocholesteroxyazepine with functionally substituted
terminal alkynes and 1, 4-butynediol was performed for the first time under the action of the …

The catalytic [6π+ 2π]‐cycloaddition of terminal alkynes to N‐carbethoxyazepine and N‐
carbophenoxyazepine catalyzed by the three‐component Co (acac) 2 (dppe)/Zn/ZnI2 …

The [6π+ 2π] cycloaddition of 2-tropylcyclohexanone to allenes and alkynes was
accomplished for the first time using the three-component catalytic system Co (acac) 2 …

Substituted bullvalenes are dynamic shape-shifting molecules that exist within complex
reaction networks. Herein, we report the synthesis of di-and trisubstituted bullvalenes and …

Starting from cyclooctatetraene, bis-homoconduritols with cis-inositol and allo-inositol (or
bicyclo [4.2. 0] octane motif) structures were synthesized. Photooxygenation of trans-7, 8 …
