Ring Opening of 1,5-Dioxaspiro[3.2]hexanes: Selective Preparation of alpha-Heterofunctionalized- beta'-hydroxy Ketones or 2,2-Disubstituted Oxetanes
J, Ndakala Albert; R, Howell Amy (Department of Chemistry, 1999)Abstract.................................. Image 2-Methyleneoxetanes have been converted into 1,5-dioxaspiro[3.2]hexanes with dimethyldioxirane. Reaction of the dioxaspirohexanes with a range of heteroatom nucleophiles, ... -
Synthesis of D -erythro-Dihydrosphingosine and D-xylo-phytosphingosine from a Serine-Derived 1,5-Dioxaspiro[3.2]hexane Template
R, Howell Amy; M, Hashemzadeh; J, Ndakala Albert (Department of Chemistry, 2002)[reaction: see text] 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 ...
