Lewis acids have recently been recognized as catalysts enabling enantioselective photochemical transformations. Mechanistic studies on these systems are however rare, either due to their absorption at wavelengths shorter than 260 nm, or the limitations of theoretical dynamic for larger complexes. In this work, we overcome challenges and employ sub-30-fs transient in UV, combination with a highl...
Two new pyrrolylquinoline-substituted heteroaromatic-containing compounds bearing a central boron bridge have been prepared by short, high-yielding sequence consisting of Suzuki-coupling 8-bromoquinoline and N-Boc 2-pyrroleboronic acid, thermolytic tert-butyloxycarbonyl deprotection, subsequent chelation (either using trifluoride or triphenylborane). Both derivatives display longer wavelength a...
BACKGROUND Development of circular economy requires significant advances in the technologies for valorisation of waste, as waste becomes new feedstock. Food waste is a particularly important feedstock, containing large variation of complex chemical functionality. Although most food waste sources are complex mixtures, waste from food processing, no longer suitable for the human food chain, may a...
