Versuchsvorschrift

and reacting the 5,6,7,8-tetrahydro-6,7-epoxy-1-naphthol in tetrahydrofuran with aqueous perchloric acid at a temperature within the range of from about 0° to about 60°C., to form trans-5,6,7,8-tetrahydro-1,6,7-naphthalenetriol XXV which can be converted to the 2,3-trans-1,2,3,4-tetrahydro-5-[2,3-(epoxy)propoxy]-2,3-naphthalenediol XXVI which in turn can be converted to the 2,3-trans-1,2,3,4-tetrahydro-5-[2-hydroxy-3-(substituted amino)propoxy]-2,3-naphthalenediol XXVII in a manner similar to that described hereinbefore.
