Medicinal plants of Brazilian native flora are consumed with little or no proof of its pharmacological properties, based only on users’ or traders’ reports. Although they are natural and, therefore, popularly considered free of side effects, medi

Asymmetric addition of organozinc compounds to carbonyl groups is one of the most useful methods for the synthesis of alcohols with high enantioselectivity. There is a wide range of chiral catalysts, although their synthesis requires more than one st

Coniferous trees of the genus Pinus (Pinaceae) are under continuous threats by numerous herbivorous insect species and pathogens attacking nearly all parts and tissues of the plants. To defend themselves, pine trees produce large amounts of oleoresin

This work objective was to use different lipases in the methyl oleate synthesis. Endophytic fungi strains of Penicillium sumatrense and Aspergillus fumigatus were isolated from castor leaves (Ricinus communis L.) in order to acquire lipases through s

In this study, we synthesized five new chiral ligands from (+) and (−)-α-pinene, which were successfully employed in the stereoselective addition of diethylzinc to aldehydes, leading to secondary chiral alcohols in up to 99% yield and 94% e.e.

A novel debenzylative approach to synthesize diaryl sulfides from aryl benzyl sulfides and aryl bromides in good to excellent yields is reported. Mechanistic studies suggest a single catalyst, derived from Pd(dba)2 and NiXantPhos, efficiently catalyz
