Photochemical reaction generates cyclopropane-fused lactones from Mannich bases, highlighting a novel synthesis method.
Key Points
The synthesis produced conformationally restricted lactones with significant efficiency and rapidity, enhancing potential applications in pharmaceuticals.
A photochemical reaction using a 370 nm LED source initiated the process, yielding an intermediate alcohol for lactonization.
The method incorporates acid-catalyzed hydrolysis and also allows for kinetic monitoring of the cyclopropanation reaction.
This approach optimizes a three-step sequence, rapidly transforming starting materials into valuable lactones for research.
