Aspectos regio- e estereoquímicos da adição de michael assimétrica via iminas quirais com centros estereogênicos pré-existentes
(2003) [Artigo de periódico]The asymmetric Michael addition reactions using chiral imines, under neutral conditions (deracemizing alkylation process), constitute one of the main methods for the stereocontrolled elaboration of quaternary carbon centers. ... -
The 1,3-dipolar cycloaddition of nitrile oxide to vinylacetic acid : computational study of transition states selectivity, solvent effects, and bicyclo formation
(2016) [Artigo de periódico]The 1,3-dipolar cycloaddition reaction is a powerful tool for the cycloaddition of nitrile oxides to olefins, and this reaction is of considerable interest to obtain isoxazolines. Density functional theory (DFT) was used ...
