Molecular iodine‐mediated functionalization of α‐Carbonyl Sulfoxonium ylides with Thiocyanates, Xanthates and Dithiocarbamates

open access: yesEuropean Journal of Organic Chemistry, Accepted Article.
In this work, we present a straightforward, rapid, and cost‐effective protocol for synthesizing three distinct classes of α‐functionalized sulfoxonium ylides—α‐xanthate, α‐thiocyanate, and α‐dithiocarbamate—via molecular iodine‐mediated reactions. This method demonstrates broad substrate tolerance, including heterocycles and steroids, delivering 25 ...

Synthesis of Bioorthogonal Mycolic Acids: Chemoselective Reduction of β‐Ketoesters Containing an Alkyne Using the Noyori Catalyst

open access: yesEuropean Journal of Organic Chemistry, Accepted Article.
The asymmetric reduction of β‐ketoesters using the Noyori catalyst is a highly effective synthetic methodology, offering excellent stereocontrol for the preparation of enantiopure b‐hydroxyesters from prochiral substrates in high yields. This reaction has been used in the total synthesis of mycolic acids, which are α‐alkyl, β‐hydroxy fatty acids ...

Counter Electrodes Based on Polyaniline/carbon Nanotube/CuxS Nanocomposites for CdS Quantum Dots‐Sensitized Solar Cells

open access: yesEnergy Technology, EarlyView.
Counter electrodes (CE) based on Polyaniline are easily prepared via electrodeposition. The polyaniline‐multi‐walled carbon nanotubes/copper sulfide (PANI‐MWCNT/CuxS) CEs exhibited better electrocatalytic activity than the other materials prepared, such as Cu and CuxS.
