Journal ArticleDOI
Sequential control over thiol click chemistry by a reversibly photoactivated thiol mechanism of spirothiopyran.
TL;DR: Polymer post-functionalization and hydrogel building with subsequent multipatterning using different maleimide molecules in a temporal sequential manner indicate that this photocontrolled Michael addition reaction can modulate the specific chemical events in a sequence.
Journal ArticleDOI
Highly efficient and solvent-free direct aldol reaction catalyzed by glucosamine-derived prolinamide
TL;DR: The prolinamide 1c was found to be an efficient organocatalyst for the asymmetric aldol reaction under solvent-free conditions and obtained in excellent chemical yields with high levels of anti diastereoselectivity and enantioselectivities.
Journal ArticleDOI
A Chiral Thiourea as a Template for Enantioselective Intramolecular [2 + 2] Photocycloaddition Reactions
TL;DR: A chiral (1R,2R)-diaminocyclohexane-derived bisthiourea was found to exhibit a significant asymmetric induction in the intramolecular [2 + 2] photocycloaddition of 2,3-dihydropyridone-5-carboxylates.
Journal ArticleDOI
Mild and Efficient Deoxygenationof Sulfoxides to Sulfides with Triflic Anhydride/PotassiumIodide Reagent System
TL;DR: In this article, the combination of triflic anhydride/potassium iodide was found to be an effective promoter for the deoxygenation of sulfoxides and gave the corresponding sulfides in excellent yield in acetonitrile at room temperature.
Journal ArticleDOI
Synthesis and characterization of thiochromone S,S-dioxides as new photolabile protecting groups.
TL;DR: 3-Arylthiochromone derivatives were synthesized as new photolabile protecting groups, in which the photoreactivity was switchable based on oxidation of the sulfur atom (sulfide and sulfone); the protected substrates released the corresponding alcohols, amines or carbonxylic acids almost quantitatively under UV-light in neutral condition.
