Napalilactona e Patilactona A são dois sesquiterpenóides espirolactônicos isolados de fontes marinhas. Esses sesquiterpenos, biogeneticamente derivados de um esqueleto carbônico do tipo aristoleno, apresentam em suas estruturas quatro centros estereogênicos contínuos e diferem apenas na substituição do heteroátomo (Cl versus OH) vizinho à unidade espiro g-butirolactônica. Como parte de um programa de pesquisa direcionado à síntese de alguns produtos naturais, descrevemos, nesse trabalho, um estudo focado no desenvolvimento de um método direto, que permitiria a preparação de um alceno funcionalizado, opticamente ativo. Esse intermediário pode ser usado para a síntese assimétrica dos dois sesquiterpenos. Devido ao elevado custo da (S)-(-)-pul...
