一个前所未有的和以前未知的光化学反应的1，3-二羰基化合物被观察到与氨基烯烃导致二氢吡喃。这种新颖的光化学反应性改变了与1，3-二羰基化合物和烯烃之间的De马约反应相关的既定范例。这种新的反应可以方便地从市售反应物中一步获得Marmycin核心。这种新的光反应的起源和范围进行了详细的初步物理和机械调查。
An unprecedented and previously unknown photochemical reactivity of 1,3-dicarbonyl compounds is observed with amino-alkenes leading to dihydropyrans. This novel photochemical reactivity changes the established paradigm related to the De Mayo reaction between 1,3-dicarbonyl compounds and alkenes. This new reaction allows convenient access to the Marmycin core in a single step from commercially available reactants. The origin and scope of this new photoreaction is detailed with preliminary photophysical and mechanistic investigations.
