An efficient synthesis method for the C-7 substituent of DU-6859a (1), which is a new-generation antibacterial quinolone carboxylic acid, was established by utilizing an enantioselective microbial reduction of 5-benzyl-4, 7-dioxo-5-azaspiro[2.4]heptane (7) to the corresponding chiral alcohol (8) as the key reaction. This synthetic method was based on use of AIPHOS (Artificial Intelligence for Planning and Handling Organic Synthesis), which is a synthesis design system that generates suitable retrosynthetic routes from the standpoints of both novelty and practicality.
利用5-benzyl-4, 7-dioxo-5-的对映选择性微生物还原,建立了新一代抗菌喹诺酮羧酸DU-6859a (1) C-7取代基的高效合成方法。氮杂螺[2.4]庚烷(7)生成相应的手性醇(8)是关键反应。该合成方法基于AIPHOS(用于规划和处理有机合成的人工智能)的使用,这是一种合成设计系统,可以从新颖性和实用性的角度生成合适的逆合成路线。
