The impact of isocyanoesters structure on enzymatic three-component Ugi reactions course has been determined. The significant promiscuous ability of enzyme in Ugi-type reaction switching between four (U-4CR) and three (U-3CR) components reactions depending on the size of used isocyanoester. The application of short-chain cyanoesters up to isocyanpropionate leading to product of three component reaction
已经确定了异氰酸酯结构对酶促三组分Ugi反应过程的影响。在Ugi型反应中,酶在4个(U-4CR)和3个(U-3CR)组分反应之间切换的显着混杂能力取决于所用异氰酸酯的大小。短链氰基酸酯的应用直至异氰酸丙酸酯仅导致三组分反应的产物,而较长的异氰基丁酸酯仅给出四组分反应的产物。研究的酶促Ugi反应的局限性是脂肪酶的底物选择性。
