Optically active β-alkyl substituted γ-lactones and whiskey lactone analogues were synthesized, and the odor properties were evaluated. During the preparation of the chiral intermediates, we found good reaction conditions for the highly enantioselective esterification of 3-arylmethyl-2-methyl-1-propanols to kinetically resolve them. The results of the olfactory evaluations of the synthesized lactones revealed that the alkyl groups on the γ-lactone rings played an important role for the odor profiles.

(Branched alkyl)-polyethoxyalkyl sulfonates, and similar compounds wherein the alkyl sulfonate moiety is replaced by a sulfate moiety, having an aromatic group on one of the branches of the branched alkyl group are provided. These compounds are surfactants which are particularly useful for chemical waterflooding, especially in high brine environments.
