Article Snippet: We report herein a chelation assisted, ring-strain-driven homoenolate interception with allenamides, proceeding through a complementary reactivity pattern�noncycloaddition and central C interception of C-pronucleophiles�distinct from previous studies.. The developed atom-economical method provides access to carbonyl-tagged enamides with high chemoand regioselectivity, offering a broad scope and significant synthetic value, as demonstrated by further diversification.. The origin of the selectivity is clarified through experimental mechanistic investigations, revealing the detailed reaction pathway proceeding through a carbopalladation event. Article Title: Copper-Catalyzed Decarboxylative Cascade Cyclization of Propargylic Cyclic Carbonates/Carbamates with Pyridinium 1,4-Zwitterionic Thiolates to Fused Polyheterocyclic Structures. Article Snippet: A copper-catalyzed decarboxylative cascade cyclization of propargylic cyclic carbonates/carbamates with pyridinium 1,4-zwitterionic thiolates is developed.. A range of fused polyheterocyclic compounds are obtained in moderate to good yields with excellent diastereoselectivities.. Of particular note is that four new bonds (two C−C, one C−O/N, one C−S) and four new stereocenters could be efficiently embedded into the tetracyclic fused scaffolds in a single step. Article Title: Organocatalytic Asymmetric Friedel-Crafts Reaction of Prochiral 3,4-Fused Pyrroles via a Desymmetrization/Kinetic Resolution Sequence. Article Snippet: An intriguing but underexplored topic is the central chirality in heteroarene derivatives originating from unsymmetrically substituted heteroarene rings.. Herein, we demonstrate the first catalytic enantioselective Friedel−Crafts reaction of prochiral 3,4fused pyrroles.. Allenamides are used as the electrophiles, and an easily available phosphoric acid was employed as the catalyst. |
