专利号:WO-2024003151-A1 优先权日:2022-06-28 标 题:Chemical synthesis platform 发明人:CRONIN LEROY 权利人:UNIV GLASGOW COURT 摘要:The invention relates to a method for generating a database for chemical syntheses and a method for performing a chemical synthesis using a database. The method for generating a database comprises generating a series of instruction sets for a series of chemical syntheses from the literature, wherein each instruction set is a machine readable and executable universal language for a chemical synthesiser; assembling the series of instructions sets within a database, and making the instruction sets available for access and autonomous execution by a chemical synthesiser. The method for performing a chemical synthesis comprises accessing an instruction set from a database, providing the instruction set to a chemical synthesiser, and autonomously executing the instruction set on the chemical synthesiser thereby to perform the chemical synthesis. The invention makes use of a standardised and step-focussed syntax to describe the chemical syntheses, and a universal synthesis automation platform.
