Cycloaddition of a nitrone to 2-aminobut-3-en-1-ol for large-scale preparation of 3-aminopiperidin-4-ols: a new asymmetric synthesis of (2R, 4R, 5S)-tetrahydropseudodistomin
Abstract
Cycloaddition of the nitrone, derived from tetradecanal, to 2-aminobut-3-en-1-ol provides a practical asymmetric synthesis of both (2R,4R,5S)-tetrahydropseudodistomin and all the stereoisomers of racemic tetrahydropseudodistomin.
