摘要:

化学计算(Chemputation)是使用通用符号语言对化学机器人编程以开展实验的过程,但文献可能存在错误,且因歧义性难以阅读。大语言模型(LLM)已在自然语言处理、机器人控制以及近期的化学领域等多个方向展现出卓越能力。尽管在合成化学数据的报告标准化与收集方面已取得显著进展,但自动复现已报道的合成方法仍是一项劳动密集型任务。\n本研究提出了一种基于LLM的化学研究智能体工作流,旨在自动验证合成文献中的实验步骤。该工作流能够自主从大量文档中提取合成步骤与分析数据,将这些步骤转换为通用XDL代码,在特定硬件配置中模拟步骤执行过程,并最终在XDL控制的合成化学机器人系统上执行该步骤。这证明了基于LLM的工作流可借助化学计算机(Chemputer)实现自主化学合成。由于XDL的抽象特性,该方法安全、可靠且可扩展——幻觉内容无法被化学计算执行,同时XDL既可被验证也可被加密。\n与以往仅覆盖工作流有限环节、依赖僵化硬编码规则或缺乏物理系统验证的研究不同,本方法提供了4个直接从合成文献提取并执行的真实合成示例。我们预计该工作流将显著提升机器人驱动的合成化学研究的自动化水平,简化数据提取流程,提高合成化学与实验化学的可复现性、可扩展性及安全性。

英文摘要:

Chemputation is the process of programming chemical robots to do experiments using a universal symbolic language, but the literature can be error prone and hard to read due to ambiguities. Large Language Models (LLMs) have demonstrated remarkable capabilities in various domains, including natural language processing, robotic control, and more recently, chemistry. Despite significant advancements in standardizing the reporting and collection of synthetic chemistry data, the automatic reproduction of reported syntheses remains a labour-intensive task. In this work, we introduce an LLM-based chemical research agent workflow designed for the automatic validation of synthetic literature procedures. Our workflow can autonomously extract synthetic procedures and analytical data from extensive documents, translate these procedures into universal XDL code, simulate the execution of the procedure in a hardware-specific setup, and ultimately execute the procedure on an XDL-controlled robotic system for synthetic chemistry. This demonstrates the potential of LLM-based workflows for autonomous chemical synthesis with Chemputers. Due to the abstraction of XDL this approach is safe, secure, and scalable since hallucinations will not be chemputable and the XDL can be both verified and encrypted. Unlike previous efforts, which either addressed only a limited portion of the workflow, relied on inflexible hard-coded rules, or lacked validation in physical systems, our approach provides four realistic examples of syntheses directly executed from synthetic literature. We anticipate that our workflow will significantly enhance automation in robotically driven synthetic chemistry research, streamline data extraction, improve the reproducibility, scalability, and safety of synthetic and experimental chemistry.
