PEP and aldolase mimicry is the key for a direct organocatalytic entry to precursors of ulosonic acids, biomolecules of enormous importance in biology, chemistry and medicine; in the key aldol reaction the dimethylacetal of pyruvic aldehyde is used as phosphoenolpyruvate (PEP) equivalent and the amino acid proline functions as an organocatalyst, imitating the enzyme.
PEP和醛缩酶的模仿是直接有机催化进入生物化学,化学和医学中极为重要的生物化学分子-乌糖酸的前体的关键。在关键的醛醇缩合反应中,丙酮醛的二甲基缩醛用作磷酸烯醇丙酮酸(PEP)当量,而氨基酸脯氨酸则充当有机催化剂,模仿该酶。
