1. Studies toward the synthesis of jungianol and construction of benzofurans by TTN-mediated ring contraction / Estudos visando à síntese do jungianol e a construção de anéis benzofurânicos utilizando TTN
This thesis describes the studies aiming at the synthesis of jungianol and the construction of benzofuranic rings. In both cases, the key-step is the reaction of thallium(III)-mediated ring contraction. Jungianol is a phenolic sesquiterpene isolated by Bohlmann et al., in 1977, from the species Jungia malvaefolia. The key-step of the synthesis could be the r
