Exploiting 3‐Methyleneisoindolinones as In Situ Generated Reactive Intermediates in the Synthesis of Tetrasubstituted Carbon Center

open access: yesAsian Journal of Organic Chemistry, EarlyView.
A straightforward method for constructing a tetrasubstituted carbon center through the in situ formation of 3‐methyleneisoindolinones as reactive intermediates has been developed. This process involves an acid‐catalyzed Meyer‐Schuster rearrangement of isoindolinone‐based propargylic alcohols, followed by an intermolecular Friedel‐Crafts alkylation ...

The Synthesis of Cyclopropyl‐Fused Tetrahydrofurans from Vinylcyclopropanes

open access: yesAsian Journal of Organic Chemistry, EarlyView.
Vinylcyclopropanes undergo iodocyclization to afford a series of oxabicyclo[3.1.0]hexanols. These substrates were shown to be useful intermediates for the construction of various cyclopropyl‐fused polycycles. Abstract The rapid synthesis of oxabicyclo[3.1.0]hexanols from various vinylcyclopropanes is described.
