The short synthesis of a series of novel chiral N-oxideorganocatalysts and their evaluation in the asymmetricallylation reaction of aromatic and α-β-unsaturated aldehydes with allyltrichlorosilane is reported. These readily modifiable organocatalysts are the first of their kind based on the tetrahydroisoquinoline framework. The chiral homoallyl products were obtained with good chemical efficiency
