چکیده
|
A three-component efficient procedure is described for the synthesis of novel α-acyloxycarboxamides containing bis(trimethylsilyl)ethenyl group from 4-[2,2-bis(trimethylsilyl)ethenyl]benzaldehyde, aromatic carboxylic acids and isocyanides, via the passerini reaction. this reaction proceeds smoothly and cleanly under mild conditions in h2o and [bmim]bf4 at room temperature and led to products in good yields. the silylated aldehyde was obtained via peterson olefination reaction of terephthalaldehyde with tris(trimethylsilyl)methyllithium in thf at 0 °c.
