3-Furyl beta-chalcogenalkyl sulfides having the structure: ##SPC1## Wherein n is 1 or 2; R.sub.2 and R.sub.3 are each selected from the group consisting of methyl and hydrogen, at least one of R.sub.2 and R.sub.3 being methyl; and R.sub.4 and R.sub.5 taken separately, are each lower alkyl, or R.sub.4 and R.sub.5 taken together complete a cycloalkyl or bicycloalkyl group, such 3-furyl beta-oxoalkyl sulfides taken alone or in admixture being useful in altering or modifying or enhancing the organoleptic properties of foodstuffs, and processes for preparing these 3-furyl beta-oxalkyl sulfides where n is 1 using the reaction: ##SPC2## Wherein X is halogen selected from the group consisting of chlorine and bromine; wherein M is alkali metal and R.sub.2, R.sub.3, R.sub.4 and R.sub.5 are each defined as above.
具有以下结构的3-呋喃基β-硫代烷基硫醚:##SPC1##
其中n为1或2;R.sub.2和R.sub.3分别选自甲基和氢的群组,其中至少一个为甲基;而R.sub.4和R.sub.5分别取自较低的烷基,或R.sub.4和R.sub.5在一起形成环烷基或双环烷基。这些3-呋喃基β-氧代烷基硫醚单独或混合使用时,有助于改变、修改或增强食品的感官特性,而制备这些3-呋喃基β-氧代烷基硫醚的过程,其中n为1,使用以下反应:##SPC2##
其中X为卤素,选自氯和溴的群组;M为碱金属,而R.sub.2、R.sub.3、R.sub.4和R.sub.5均如上所定义。
