RESUMO

Steroid and terpene chemistry still have a great impact on medicinal chemistry. Therefore, the development of new reactions or "greener" processes in this field is a contemporaneous issue. In this review, the use of bismuth(III) salts, as "ecofriendly" reagents/catalysts, on new chemical processes involving steroids and terpenes as substrates will be focused. Special attention will be given to some mechanistic considerations concerning selected reactions.
