It has been proposed that the intramolecular reaction of the carbonyl hydrate of methylacetoin diethyl phosphate (1) may serve as a model for the latter part of such a mechanism. In basic solution, 1 reacts rapidly to give two sets of products that can be accounted for by a mechanism involving addition of a hydroxyl group of the carbonyl hydrate to the adjacent phosphate. The rapid reaction of the
生物素与碳酸氢盐和 ATP 的酶促反应产生 N-羧基生物素、ADP 和磷酸盐。反应中的中间体未知。有人提出,甲基乙偶姻磷酸二乙酯 (1) 的羰基水合物的分子内反应可以作为这种机制后半部分的模型。在碱性溶液中,1 迅速反应生成两组产物,这可以通过一种机制来解释,即羰基水合物的羟基加成到相邻的磷酸盐上。非烯醇化酯与碱的快速反应排除了涉及烯醇化途径的反应的早期机制建议
