- Y is selected from the group consisting of alkyl of 1 to 18 carbon atoms optionally substituted with a halogen; and
- --CY.sub.3 ' and a .beta.,.gamma. bond together with Y may be included in A and Y' is bromine or chlorine.
- 2. A hemiacetal in all possible isomeric forms of the formula ##STR21## wherein A, of which .beta.,.gamma. bond can be part, represents an optionally substituted hydrocarbon chain selected from the group consisting of ##STR22## wherein Y.sub.1 and Y.sub.2 are individually selected from the group consisting of hydrogen, fluorine, chlorine, bromine and alkyl of 1 to 6 carbon atoms, or Y.sub.1 and Y.sub.2 together with the carbon to which they are attached form a carbon homocycle of 3 to 7 carbon atoms and Z is selected from the group consisting of hydrogen, chlorine, bromine and iodine.
- 3. A compound of claim 1 seleted from the group consisting of (1R,2S,4R,5S)6,6-dimethyl-4-[2-methyl-2-propyl]-3-oxa-bicyclo(3,1,0)hexa-2-ol and its antipodal form, (1R,2S,4R,5S)6,6-dimethyl-4-trichloromethyl-3-oxa-bicyclo(3,1,0)hexan-2-ol and its antipodal form and (1R,2S,4R,5S)6,6-dimethyl-4-tribromo-methyl-3-oxa-bicyclo(3,1,0)hexan-2-ol and its antipodal form.
- 4. A compound of claim 2 selected from the group consisting of (1R,2S,5S)6,6-dimethyl-3-oxa-bicyclo-(3,1,0)hexan-2-ol and its antipodal form, (3aR,4R,7S,7aS,1S)tetrahydro-4,7-methano-isobenzofuran-1-ol and its antipodal form, racemic 9,10,11,12,14,15-hexahydro-9,10-[3',4']-furananthracene-12-ol, (11R,12R,15S)9,10,11,12,14,15-hexahydro-9,10,-[3',4']furananthracene-12-ol and its antipodal form, racemic 6-bromohexahydro-3,5-methano-2H-cyclopenta[b]furan-2-ol, (2S,3S,3aR,5S,6S,6aS)6-bromo-hexahydro-3,5-methano-2H-cyclopenta[b]furan-2-ol and its antipodal form and (2S,3R,3aR,5S,6aR)hexahydro-3,5-methano-2H-cyclopenta[b]furan-2-ol and its antipodal form.
