Abstract
AbstractThe bicyclo[1.1.1]pentane (BCP) scaffold is useful in medicinal chemistry, and many protocols are available for synthesizing BCP derivatives from [1.1.1]propellane. Here, we report (1) the α‐cyclodextrin (α‐CD) encapsulation of BCP derivatives, affording a stable, readily storable material from which BCPs can be easily and quantitatively recovered and (2) new and simple protocols for deiodination reaction of 1,3‐diiodo BCP to afford [1.1.1]propellane in protic/aprotic/polar/non‐polar solvents. The combination of these methodologies enables simple, on‐demand preparation of [1.1.1]propellane in various solvents under mild conditions from α‐CD capsules containing 1,3‐diiodo BCP.
