Organocatalytic asymmetric desymmetrization of cyclopentene-1,3-diones via a formal diaza–ene reaction with donor–acceptor hydrazones Herein we disclose a catalytic asymmetric desymmetrization of cyclopentene-1,3-diones via a formal diaza–ene reaction/tautomerization with donor–acceptor hydrazones. The H8-TRIP catalyst was found to ...

We ended the week with a deep dive (in the seminar room and beyond) into #photochemistry with Paolo Melchiorre's talk on #organocatalytic intermediates, which can directly enter an electronically excited state by absorbing visible light, and the potential of natural #biocatalytic intermediates.
