Novel sphingenine and derivatives thereof.

摘要

A sphingenine and derivatives thereof herein provided are represented by the following general formulas (I) and (II): in the formulas (I) and (II), R<1> represents a hydrogen atom, an acetyl group or a methanesulfonyl group; R<2> represents a hydrogen atom or an ethoxyethyl group; R<3> represents an azido group, an amino group, an alkylamido group, an arylamido group, an aralkylamido group or a tetracosanamido group; R<4> represents a hydrogen atom or an ethoxyethyl group; EE represents an ethoxy ethyl group; and n is an integer ranging from 1 to 22. These sphingenine and derivatives thereof are very useful as intermediates for synthesizing glycolipids and gangliosides which are effective as markers of tumours, in particular, in the preparation of ceramide parts of the glycolipids and gangliosides.
