Abstract: Compounds of the general formula I: ##STR1## wherein R.sub.1 and R.sub.2 are equal or different alkyl-, alkoxyalkyl-, or aryl groups, or together form a ring; R.sub.3 is an allyl or benzyl radical; and R.sub.4 and R.sub.5 represent hydrogen, alkyl, alkoxyalkyl, alkenyl or further compounds of the formula II: ##STR2## wherein R.sub.1, R.sub.2, R.sub.4 and R.sub.5 have the meaning indicated above and R.sub.6 stands for hydrogen or methyl or to compounds which are modified by the addition of hydrogen to at least one olefinic or carbonylic double bond of compounds of the general formula I or II. The invention also relates to a process for preparing the new compounds. The compounds of the general formula II are obtained by thermal treatment of a selection of compounds of formula I, for which R.sub.3 stands for the allyl or methallyl radical. The compounds according to the invention are used as fragrant and flavoring substances.

Abstract: The S-enantiomer of 3-chloro-1,2-propanediol is prepared by reaction of a chlorodeoxy-D-saccharide having the partial structure. ##STR1## to cleave the glycol, reduce the aldehyde so formed to an alcohol, and hydrolyse the alcohol under mild acidic conditions.
