Abstract
Dialkyl-substituted .beta.-resorcylic acid esters having the structure: ##STR1## wherein each of R.sub.1, R.sub.2, and R.sub.3 is lower alkyl may be readily prepared by reacting the corresponding dihydroresorcylic acid esters with sulfuryl chloride. These compounds, particularly, methyl 3,6-dimethyl-resorcylate and methyl 3-ethyl-6-methyl-resorcylate, have oakmoss-like odors rendering them valuable as perfume ingredients.
