Chiral compounds containing a tetrahydropyran ring

Abstract

Described herein are chiral compounds of the formula I ##STR1## where R.sup.1 is hydrogen or --Y--Z--Y.sup.1, R.sup.2 is ##STR2## and X is hydrogen, fluorine, chlorine, bromine, iodine, hydroxyl or OR.sup.1, where Y is a direct bond, CO or C.sub.2 - to C.sub.8 -alkylene in which nonadjacent carbon atoms may be replaced by O, CO, COO or OCO, Z is a group containing one or more saturated or unsaturated carbocyclic or heterocyclic rings, Y.sup.1 is C.sub.1 - to C.sub.15 -alkyl, C.sub.2 - to C.sub.15 -alkenyl, C.sub.1 - to C.sub.15 -alkoxy, C.sub.2 - to C.sub.15 -alkenyloxy, C.sub.1 - to C.sub.15 -alkanoyloxy or C.sub.3 - to C.sub.15 -alkenoyloxy, it being possible for nonadjacent carbon atoms in these radicals to be replaced by oxygen, OCO or COO, and n is 0, 1 or 2.
