Progress toward the synthesis of the transtaganolide/basiliolide natural products: an Ireland–Claisen approach
摘要:
Efforts toward the synthesis of the transtaganolide natural product family are described. A highly efficient Ireland-Claisen/Diels-Alder approach has been developed, which rapidly constructs the highly oxygenated and stereochemically rich core of these natural products.

A surprising turn of events: Mechanistic studies, including trapping, control, and isotope‐labeling experiments, led to the proposal of a rearrangement mechanism involving oxidation of aliphatic CH bonds (see scheme; TMEDA=tetramethylethylenediamine).

Addition of co-catalytic Cy2NH to Mn-catalysed C–H bond activation reactions suggests that the conjugate acid, Cy2NH2X, influences catalysis. Here, acids are shown to positively influence C–H bond alkenylation catalysis involving alkynes. For certain types of alkynes an acid additive is critical to catalysis. In stark contrast, acids retard catalysis involving acrylates. [Cy2NH2]X salts also play a key
