The key compound responsible for the aroma of bread, 6-acetyl-1,2,3,4-tetrahydropyridine (1), has been constructed in an efficient three-step procedure from 2-piperidone in an overall yield of 56%. Compound 1 was liberated in the final step under basic conditions. A related synthetic route produced 2-acetyl-1-pyrroline (2), the principal component of cooked rice, in 10% overall yield.
负责面包香气的关键化合物6-乙酰基-1,2,3,4-四氢吡啶(1)是由2-哌啶酮以有效的三步法制备的,总收率为56%。在最终步骤中,在碱性条件下释放出化合物1。一种相关的合成路线生产了米饭的主要成分2-乙酰基-1-吡咯啉(2),总产率为10%。
