摘要
以醛/酮与1,2-乙二硫醇或1,2-丙二硫醇在对甲苯磺酸催化下反应,合成了10种2-取代-1,3-二硫杂环戊烷,产率62.8%~87.8%;其中,2-正丙基-1,3-二硫杂环戊烷产率达87.8%,纯度99.5%。经元素分析、FTIR、GC-MS和’HNMR确定了10种产物的结构。香气评价结果表明:合成的2-正丙基-1,3-二硫杂环戊烷具有花香、肉汤香气,可用于食品香精和调味料中;其余9种2-取代-1,3-二硫杂环戊烷具有肉香、葱蒜香和萝卜香。
Ten 2-substituted-I, 3-dithiolanes flavoring compounds were synthesized by reactions of aldehydes or ketones with 1,2-ethanedithiol or 1,3-propanedithiol, catalyzed by ptoluenesulfonic acid. The yields were among 62.8%-87.8%. Yield of 2-n-propyl-1,3-dithiolane was 87.8% with a purity of 99.5%. Structures of the ten synthesized compounds were identified by data of elemental analysis, FTIR, 'H NMR and GC-MS. Organoleptic evaluation showed that 2-n-propyl-1,3-dithiolane had a floral, broth character and was suitable for flavors and seasonings, the other nine 2-subsitituted-1,3-oxathiolanes had meat, onion, garlic and radish characters.
