, 2014 [[abstract]]The treatment of a series of 1-aryl-2,2-dihalocyclopropanes with t-BuOK at -10 C produces the corresponding 1-aryl-2-halocyclopropenes, which react with cyclopentadiene to produce fairly good yield of [4+2]-cycloaddition products with more ...

Angewandte Chemie, EarlyView.A chemoenzymatic methodology is described that provided a panel of 6‐sulfo sialyl Lewisx‐containing glycans that were probed for receptor specificity of MERS‐CoV. Although the fucoside of 6‐sulfo‐SLex does not directly interact with the spike, it pre‐organizes the molecule into a conformation to allow a salt bridge between the sulfate and the ...

Angewandte Chemie, EarlyView.Calderoselectivity is established as a stereochemical principle for sigmatropic rearrangements. A homoannulene‐based chiroptical photoswitch undergoes a photochemical [1,11] sigmatropic rearrangement with control of the acyl movement on top of the cyclic π system.

Engineering Rapid Payload Release Rate in 1,6‐Elimination Processes of Self‐Immolative Linkers
Angewandte Chemie, EarlyView.The payload release rate of self‐immolative linkers was greatly improved through stabilization of an intermediate carbocation, thereby achieving an up to 10 000‐fold improvement in rate constant. Furthermore, lipophilicity was identified as another factor that affects the release rate. This new strategy is applicable to different payloads and different
