We introduced a feasible way to fabricate enantiopure chiral crystal aggregates directly from their racemic solution and their chirality can be tuned by the molar masses of polymeric additives.

We report the aza-Hock rearrangement of benzyl alcohols with arylsulfonyl hydroxylamines (ArSO2ONHR) in fluorinated alcohols (HFIP or TFE), delivering anilines in good to excellent yields.

Roaming is a reaction mechanism generating molecular products via wondering motions. The atomic movements during the roaming have never been directly observed. Here, we explore the atomic movements of a roaming-mediate isomerization using femtosecond X-ray liquidography.

Endoperoxidase NvfI catalyzes the incorporation of “three” oxygen atoms, including an endoperoxide and a hydroxyl group, into its substrate asnovolin A, in a single enzyme turnover reaction through a different mechanism from those of previously characterized endoperoxidases.
