  • Process for the stereospecific synthesis of indole derivatives
    Patent number: 4806655
    Abstract: The present invention relates to a process for the stereo-specific synthesis of indole derivatives of formula: ##STR1## which consists in using 3-tosyloxy-1,2-O-isopropylidenepropane-1,2-diol (II) in an optically pure form in order to introduce the asymetric carbon C* of compound (I). Compound (II) is condensed with a suitable primary amine in order to prepare an oxazolidinone and condensation with a suitable phenol, and the oxazolidinone ring is then opened to form an indole compound (I).
