摘要

本文报道了一步法合成丙交酯的方法，取代了传统的两步法。选择合适的酸性催化剂聚磷酸（PPA），优化反应条件，收率达97%。此外，这种新的一步策略消除了对金属催化剂的需求，不需要高温条件，从而避免了外消旋化的问题。简单的一步策略提供了效率，可持续性和产品质量改进的组合，使其成为丙交酯合成的现代实用方法。

Efficient One-Step Synthesis of Lactide with High Yield and Selectivity Using Brønsted Acid Catalysis

In this work, a one-step method synthesis of lactide is reported instead of the traditional two-step method. The selection of a suitable acid catalyst polyphosphoric acid and optimization of reaction conditions result in a yield of 97%. Moreover, this new one-step strategy eliminates the need for metal catalysts and does not require high-temperature conditions, thereby avoiding the issue of racemization. The simple one-step strategy offers a combination of efficiency, sustainability, and product quality improvements, making it a modern, practical approach to lactide synthesis.
