Multiple Sampling Capsule Robot for Studying Gut Microbiome

Advanced Intelligent Systems, EarlyView.
A multiple sampling capsule robot (MSCR) is developed for longitudinal gut microbiome analysis. Employing electromagnetic field control, the MSCR can locomote actively, precisely align the selected channel, and collect up to six microbiome samples with minimal cross‐contamination.

Synthesis of Benzodithieno[5.5.5.6]Fenestranes: Unexpected Epimerization and Regiochemical Outcomes

Asian Journal of Organic Chemistry, EarlyView.
Isomeric [5.5.5.6]fenestranes annulated with one benzene and two thiophene rings are accessible via di‐2‐ and di‐3‐thienylspirane intermediates. The key double cyclization step involves surprising stereoselectivity and regioselectivity. In particular, cis‐di(2‐thienyl)spirane precursors lead to the all‐cis‐fenestrane skeleton by an unexpected acid ...
