Synthesis of cyclopropyl-substituted furans by Brønsted acid promoted cascade reactions [PDF]
, 2015 Chloroacetic acid promotes an efficient and diastereoselective intramolecular cascade reaction of electron-deficient ynenones to deliver products featuring a 2,3,5-trisubstituted furan bearing a fused cyclopropyl substituent at the 5-position ...

A Fluorogenic Hydrazino‐Pictet–Spengler Reaction in Live Cells
Angewandte Chemie, EarlyView.A fluorogenic hydrazino‐Pictet–Spengler (HIPS) ligation reaction is used to label lipid‐derived aldehydes under wash‐free conditions in live cells. This innovative technique enables wash‐free imaging within biological systems, offering invaluable insights into the extent and localization of oxidative stress.

Angewandte Chemie, EarlyView.A zeolite‐catalyzed strategy enables size‐selective monoacetalization of sugars and polyols in a single step by leveraging pore confinement to distinguish between mono‐ and multi‐substituted species. This broadly applicable method avoids protection steps and excess reagents, opening new routes to bio‐based amphiphiles with strong surface activity and ...

Pd-catalyzed enantioselective aerobic oxidation of secondary alcohols: Applications to the total synthesis of alkaloids [PDF]
, 2008 Enantioselective syntheses of the alkaloids (-)-aurantioclavine, (+)-amurensinine, (-)-lobeline, and (-)- and (+)-sedamine are described. The syntheses demonstrate the effectiveness of the Pd-catalyzed asymmetric oxidation of secondary alcohols in ...

Angewandte Chemie, EarlyView.By combining gas‐phase rotational spectroscopy and quantum chemistry calculations, we explore how a prototype molecular photoswitch is affected by microhydration. This study unveils the theory‐breaking structural features of camphorquinone oxime, the concerted dynamics of the surrounding water network, and how the oxime subunit actively steers the ...
