Synthesis and Structure of Neopentyl Sodium: A Hydrocarbon‐Soluble Reagent for Controlled Sodiation of Non‐Activated Substrates

Angewandte Chemie, EarlyView.
Displaying strong controlled metalating power, hydrocarbon‐soluble sodium neopentyl can deprotonate challenging non‐activated arenes and alkenes, with sodiated intermediates successfully undergoing onward functionalisation reactions. By characterising key reaction intermediates, and running computational studies on models, insight has been gained on ...

The Synthesis of Cyclopropyl‐Fused Tetrahydrofurans from Vinylcyclopropanes

Asian 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.
