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.

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
