多彩_なCO2の複雑な製品への変革:ワンポット2段階戦略

Executive Industry Relevance

This method enables the transformation of CO₂ into complex chiral molecules through a one-pot two-step strategy, offering a sustainable route to value-added chemical intermediates. The ability to generate stereodefined products from a single carbon source supports early-stage target validation by providing access to diverse, enantiomerically enriched scaffolds. The mild reaction conditions and short overall reaction time enhance practicality for discovery workflows focused on mechanistic de-risking and lead identification.
