The SBIP-catalyzed reaction of benzofuranone alkene (I) with allenes (II) affords γ-addition [3 + 2] cycloadducts (III) with high enantioselectivity, whilst the reaction with allenes (IV) gives rise to α-addition [3 + 2] cycloadducts (V). [ABSTRACT FROM AUTHOR]

A novel cinchona alkaloid derived amine catalyzes the [3 + 2] cycloaddition of oxindoles with 2-butenedioc acid esters to produce spirooxindoles with high diastereo-and enantioselectivity. [ABSTRACT FROM AUTHOR]

Novel amine-catalyzed tunable cycloadditions between allenoates and dithioesters, providing a divergent synthesis of 2,3-dihydro-1,4-oxathiines and enantioenriched thietanes is reported. [ABSTRACT FROM AUTHOR]

The title reaction affords a series of fully functionalized pyrrole derivatives (III) and (V) via rhodium azavinyl carbene intermediates. [ABSTRACT FROM AUTHOR]

The first example of the highly enantio- and diastereoselective 1,3-dipolar cycloaddition of azomethine imines with δ-substituted allenic esters is demonstrated using a chiral (S)-Me-f-KetalPhos (FEC) catalyst under optimized conditions. [ABSTRACT FROM AUTHOR]

A novel cycloisomerization/rearrangement of newly synthesized yne-vinylidenecyclopropanes (I) and (III) catalyzed by a sterically hindered gold catalyst is reported. [ABSTRACT FROM AUTHOR]

The article presents chemical equations related to the article "Enantioselective Synthesis of Spirooxindoles: Asymmetric [3 + 2] Cycloaddition of (3-Isothiocyanato)oxindoles with Azodicarboxylates" by Y. Jiang and others, published in the periodical "European Journal of Organic Chemistry" in 2013.

This novel three component reaction gives an easy access to isoquinoline derivatives via a 1,4-dipolar cycloaddition reaction. [ABSTRACT FROM AUTHOR]

The reactions are catalyzed by a novel Cinchona alkaloid-derived organocatalyst and different spirocyclic products are obtained depending on the reaction conditions and the ratios of reagents. [ABSTRACT FROM AUTHOR]

A facile protocol for preparation of bicyclo[4.2.0] heterocycles containing a nitrogen atom is developed starting from allene-alkylidenecyclopropanes. [ABSTRACT FROM AUTHOR]
