title: A general and concise asymmetric synthesis of sphingosine, safingol and phytosphingosines via tethered aminohydroxylation.
abstract: A novel, practical and efficient enantioselective synthesis of sphingoid bases, l-threo-[2S,3S]-sphinganine (safingol), l-threo-[2S,3S]-sphingosine, l-arabino-[2R,3S,4R] and l-xylo-[2R,3S,4S]-C(18)-phytosphingosine is described. The synthetic strategy features the Sharpless kinetic resolution and tethered aminohydroxylation (TA) as the key steps.
