TL;DR: To the authors' knowledge, this is the first example in which the NH unit of indole is used as a directing group for an intramolecular C(sp2)-H bond functionalization to give benzo[a]carbazole derivatives.

TL;DR: An efficient one-pot synthetic protocol has been proposed for the synthesis of luntonin F from easily available starting materials usingiodination, Kornblum oxidation, and annulation through a rational logical design.

TL;DR: The first phosphine-catalyzed [4 + 2] annulation of γ-substituted allenoates with 2-arylidene-1H-indenes-1,3(2H)-diones is disclosed, offering a powerful approach to the construction of highly substituted spiro[4.5]dec-6-ene skeletons in excellent yields, and with complete regioselectivity and high diastereoselectivities.

TL;DR: An enantioselective formal [3+3] annulation reaction of cyclic ketones with enones has been developed and it is shown that the reactions afford bicyclo [3.3.1] adducts in moderate to good yields with good to high enantiOSElectivities under mild conditions.

TL;DR: A phosphine-catalyzed [4 + 3] annulation of modified allylic carbonates with methyl coumalate was developed and offered a powerful method for the construction of bicyclo[3.2.2]nonadiene skeleton with high stereoselectivity.
