Enantiomerically Pure Vinylcyclopropylboronic Esters

Vinylcyclopropanes are versatile intermediates and products in organic synthesis. The corresponding enantiomerically pure boronic esters should lead to highly flexible building blocks with a variety of applications. A detailed study towards the selective

Synthesis of dictyopterene A

The total synthesis of dictyopterene A was accomplished via an enantiomerically pure cyclopropylboronic ester building block. Crucial olefination steps were carried out employing the Julia-Kocienski as well as the Wittig reactions. The Matteson homologation was the final key step for the total synthesis.

Synthesis of enantiomerically pure vinylcyclopropylboronic esters via cross-metathesis

The potent antibiotic ambruticin caused us to investigate two new aspects of cyclopropylboronic ester chemistry: we established the analytical basics for all 1,2,3-trisubstituted diastereoisomers as well as the cross-metathesis as a tool to synthesise vinylcyclopropylboronic esters.
