 note = {application/pdf, The new hybrid-type squaramide-fused amino alcohol containing both a Bronsted basic site and hydrogen bondingsites in the molecule showed a high catalytic activity as an l organocatalyst in the enantioselective domino Michael addition/cyclization reaction of oxoindohnes with cyclic 1,3-etones to afford'the chiralsproonjugate oxindoles featuring 2-aminopyrans fusing with l carbo-heterocyclic ring systems with l excellent chemical yields (up Ito 98%) and enantioselectivities (up to 95% ee). The obtained chiral spiroconjugated 2-aminopyrans bearing quaternary stereogenic carbon center could be used as l synthetic precursors for several natural products that ave a broad spectrum Iof fascinating biological activities.},
