Caylobolide B: Structure Revision, Total Synthesis, Biological Characterization, and Discovery of New Analogues

Angewandte Chemie International Edition, EarlyView.
Marine polyhydroxylated macrolides’ drug discovery potential is limited by structural complexity and scarce material supply, hindering structure assignment, synthesis, and biological studies. Here, we present an integrated workflow that combines chemogenomic profiling, ultra‐high‐resolution NMR‐guided structural revision and stereochemical assignment ...

Enantioselective Oxidative Spirocyclization of Biaryl Hydroxy Carboxylic Acids: Enantioselective Synthesis of (–)‐Arnottin II

Chemistry – An Asian Journal, EarlyView.
The first catalytic and metal‐free enantioselective synthesis of (–)‐arnottin II is reported. A one‐pot hydrolysis/oxidative spirolactonization sequence, catalyzed by a chiral hypervalent iodine(I/III) complex under phosphate‐buffered conditions, establishes efficient control of the unstable biaryl hydroxy carboxylic acid (BHCA) intermediate, to afford

Selective N‐Alkylation of Unprotected Amino Sugars by Alcohols. Application to the Synthesis of Sugar‐Based Surfactants

ChemistryEurope, EarlyView.
A borrowing hydrogen strategy using an NHC‐Ir(III) catalyst enables selective N‐functionalization of unprotected amino sugars using alcohols as alkylating agents. The use of unprotected substrates avoids extra steps of protection/deprotection, minimizing waste generation.
