RESUMO
We have developed an automated photochemical microfluidics platform that integrates a 1 kW high-pressure Hg vapor lamp and allows for analytical pulse flow or preparative continuous flow reactions. Herein, we will discuss the use of this platform toward the discovery of new chemotypes through multidimensional reaction screening. We will highlight the ability to discretely control wavelengths with optical filters, allowing for control of reaction outcomes.

The reaction of a sulfamate ester derived rhodium nitrenoid species with an alkyne produces a versatile intermediate, capable of cascading into a wide variety of secondary transformations. The nature of the intermediate has been probed by reactivity studies, and the synthetic utility of the cascade process, which facilitates the construction of complex heterocyclic structures from remarkably simple acyclic precursors, is highlighted.
