Part 1: Progress Toward the Total Synthesis of Platensimycin. Part 2: Aromatic Ions: Carbon-Based Nucleofuges and Chiral Cyclopropenones and Formamides
… of proficient carbon nucleofuges for the Tsuji-Trost allylation, and the use of chiral cyclopropenones and formamides for the kinetic resolution of alcohols by chlorodehydration. The first chapter describes efforts in the total synthesis of platensimycin. The synthesis attempted to use a …

Aplikace substituovaných pyranonů v chemii dendralenů a totální syntéze přírodních látek
… catalyzed reactions, Migita-Stille coupling and Tsuji-Trost allylic transposition. The products obtained were applied in the synthesis of cross-conjugated heterocyclic [3] and [4]dendralenes, providing structurally complex mono- to tris-cycloadducts with a suitable dienophile through …

Fused and spiro furanones from tetronic acid synthons: Oxa and azacycles featuring the butenolide ring
… two identical allyl residues were obtained by Tsuji-Trost-type Pd-catalysed allylation of either 4-O-allyltetronates or 3-allyltetronic acids. Pd assisted allylation of sodium 3-allyltetronate with a second allyl acetate gave mixed derivatives as did the Claisen rearrangement of 4-O-allyl …

3-Funktionalisierung von Tetron- und Tetramsäuren - Beiträge zur Totalsynthese von Bakkenolid-A und Macrocidin A
… Reaktionspartner für eine regioselektive Tsuji-Trost-Reaktion gefunden werden. Eine vollständige Synthese von Bakkenolid A scheiterte jedoch aufgrund unüberwindbarer, sterischer Hinderung bei der anschließenden Diels-Alder Reaktion. Im zweiten Teil dieser Arbeit wurde die Totalsynthese von …

Anion Relay Cyclopropanation and Aryl Vinyl Cyclopropane Cope Rearrangements
… a nascent allylic alcohol following an initial Tsuji-Trost allylation between a carbon nucleophile and a vinyl epoxide. This reaction constitutes the latest example of retro-Claisen activation of allylic alcohols presented by our group, and a novel application of anion relay chemistry. Of note …
