Synthesis of D-erythro-sphingosine and D-erythro-ceramide.
A 1,2-metallate rearrangment of a higher order cuprate derived from an alpha-lithiated xylal derivative and tridecyllithium is the key step in a synthesis of D-erythro-sphingosine and ceramide. A convenient method for preparing alpha-lithiated glycals from alpha-phenylsulfinyl glycals is also described.
