Procedure stereospecific synthesis of indole derivatives.

摘要

The present invention INTENDED TO A stereospecific method of synthesis of indole derivatives of formula (I). This procedure consists in using 3-tosyloxy-1,2-O-isopropylidene 1,2-propanediol in a form optically pure to introduce asymmetric carbon * C compound (I). THIS IS THE EQUALLY AS INVENTION END INTERMEDIARY oxazolidinone of formula (IX) wherein R5 is H or a group (II).
