1. Estudo do potencial enzimático de micro-organismos endofíticos para a biotransformação de produtos naturais e análogos sintéticos / Study of endophitic microorganisms potential on the biotransformation of natural products
The endophytic microorganisms Penicillium griseoroseum, Penicillium brasilianum, Aspergillus flavus e Aspergillus aculeatus have shown to be very efficient in order to perform the most diferenciated biotransformation reactions. The fungi Penicillium griseoroseum has presented an elevated desmethylation selectivity of the caffeine substrate besides the desmet

2. Conformational analysis and electronic interaction study of some ortho-substituted alpha-ethylsulfonylacetophenones; and the oxidative rearrangement study of some ortho-substituted alpha-ethylthioacetophenones / Análise conformacional e estudo das interações eletrônicas em alfa-etilsulfonilacetofenonas-orto-substituídas e o estudo do rearranjo oxidativo de alfa-etiltioacetofenonas-orto-substituídas
The first part of this thesis reports the conformational study of some -ortho-substituted α-ethylsulfonylacetophenones o-X-PhC(O)CH2SO2Et (X= OMe 1, Me 2, F 3, Cl 4, Br 5 e NO2 6) through the analysis of the carbonyl stretching IR band in solvents of increasing polarity supported by HF/6-31G** ab initio computations. The good match between IR frequencie
