consecutive stereoselective aminoallylations of appropriate aldehydes with chiral tert-butanesulfinamide and in situ generated allyl indium species. The absolute configuration of the carbon stereogenic center at the aminal moiety is thermodynamically controlled. This was ascertained on the basis of an exhaustive DFT configurational study of tetraponerines, which fulfils the lack of detailed structural information

requires only two synthetic operations with one-column chromatography and is readily scaled up. The versatility of these chiral building blocks was exemplified by the total or formal synthesis of some natural and unnatural alkaloids.
