1. Synthesis of 5-monobromocavernicolin and 3-bromoverongiaquinol : addition of carbon nucleophiles to cyclic oxonum ions under solvent-free conditions / Sintese da 5-monobromocavernicolina e do 3-bromoverongiaquinol : reações de adição de nucleofilos de carbono a ions oxonios ciclicos em sistemas sem solvente
This dissertation is divided in two parts. The first part presents the synthesis of natural products isolated from marine sponges. The second part presents investigations on the addition of carbon nucleophiles to cyclic N-acyliminium and oxonium ions under solvent-free conditions. The natural product 5-monobromocavernicolin was isolated for the first time fr
