title: A general, efficient and stereospecific route to sphingosine, sphinganines, phytosphingosines and their analogs.
abstract: Sphingosine, sphinganines and phytosphingosines and their analogs were synthesized by an aldol condensation between an iminoglycinate bearing a (+)-(1R,2R,5R)-2-hydroxy-3-pinanone group as chiral auxiliary and an appropriate aldehyde. All condensations proceeded with excellent enantioselectivity to generate the (2S,3R)-D-erythro structures in good yields.
