Diels–Alder Versus Michael Adducts of 2‐Methylfuran and Maleate: Consecutive Synthetic Access to Both Product Types

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
More than a century after Albrecht's original proposal, an unexpected synthetic relationship between the historically misassigned Michael adduct type and the genuine Diels–Alder product is revealed. Experimental and theoretical studies show that the Michael adduct is not formed directly from the diene and dienophile, but instead arises through ...

Creativity and its link to epilepsy

open access: yesEpilepsia Open, EarlyView.
Abstract Creative thinking represents one of our highest‐order cognitive processes, involving multiple cortical structures and an intricate interplay between several cortical and subcortical networks. It results in novel ideas that translate to useful products or concepts. The evolutionary purpose of creativity is therefore apparent, as it advances our
