Synthesis of D-erythro-dihydrosphingosine and D-xylo-phytosphingosine from a serine-derived 1,5-dioxaspiro[3.2]hexane template

Ndakala, Albert J.,Hashemzadeh, Mehrnoosh,So, Regina C.,Howell, Amy R.

, p. 1719 - 1722 (2002)

Matrix presented A serine-derived 1,5-dioxaspiro[3.2]hexane template is shown to be a useful precursor for both aminodiol and aminotriol sphingoid bases by its conversion to D-erythro-dihydrosphingosine and D-xylo-phytoshingosine.
