Intramolecular Pd-Mediated Processes of Amino-Tethered Aryl Halides and Ketones: Insight into the Ketone α-Arylation and Carbonyl-Addition Dichotomy. A New Class of Four-Membered Azapalladacycles
TL;DR: The dichotomy between ketone alpha-arylation and carbonyl-addition in the reactions of omega-(2-haloanilino) alkanones has been rationalized by the intermediacy of unprecedented four-membered azapalladacycles, from which X-ray data and chemical behavior are reported.
Journal ArticleDOI
A General Synthetic Entry to Strychnos Alkaloids of the Curan Type via a Common 3a-(2-Nitrophenyl)hexahydroindol-4-one Intermediate. Total Syntheses of (±)- and (−)-Tubifolidine, (±)-Akuammicine, (±)-19,20-Dihydroakuammicine, (±)-Norfluorocurarine, (±)-Echitamidine, and (±)-20-Epilochneridine1
TL;DR: In this paper, a general strategy for the synthesis of pentacyclic Strychnos alkaloids with the curan skeleton has been developed, which utilizes 3a-(2-nitrophenyl)hexahydroindol-4-one (23), which was prepared from 2-allyl-2-2-(1,3-cyclohexanedione (15), as the common, pivotal intermediate.

TL;DR: Aeruginosins represent a group of peptide metabolites isolated from various cyanobacterial genera and from marine sponges that potently inhibit different types of serine proteases that are characterized by the presence of a 2-carboxy-6-hydroxyoctahydroindole (Choi) moiety.
Journal ArticleDOI
Synthesis of the 4-Azatricyclo[5.2.2.04,8]undecan-10-one Core of Daphniphyllum Alkaloid Calyciphylline A Using a Pd-Catalyzed Enolate Alkenylation
TL;DR: The ABC ring system of the natural product calyciphylline A has been synthesized through a palladium-catalyzed intramolecular coupling of an amino-tethered vinyl bromide with a ketone using potassium phenoxide as the base to generate the C-ring.
Journal ArticleDOI
Palladium-catalyzed intramolecular coupling of vinyl halides and ketone enolates. Synthesis Of bridged azabicyclic compounds
TL;DR: The palladium-mediated intramolecular coupling of amino-tethered vinyl halides and ketone enolates is a useful methodology for the synthesis of nitrogen heterocycles and constitutes a new synthetic entry to the 2-azabicyclo[3.3.1]nonane framework.
