Asymmetric Cyclization of 2′‐Hydroxychalcones to Flavanones: Catalysis by Chiral Brønsted Acids and Bases
TL;DR: In this paper, the authors investigated the possibility of using camphorsulfonic acid as chiral Bronsted acid catalysts for asymmetric cyclization of 2-hydroxychalcones to flavanones.

β-Cyclodextrin in water: highly facile biomimetic one pot deprotection of phenolic THP/MOM/Ac/Ts ethers and concomitant regioselective cyclization of chalcone epoxides and 2′-aminochalcones
TL;DR: In this article, a mild and efficient one-pot deprotection of THP/MOM/Ac/Ts ethers and the concomitant cyclization of chalcone epoxides to 2-hydroxyindanones or 2′-aminochalcones to aza-flavanones using β-cyclodextrin in water has been developed.

An improved procedure for the isomerisation of 2'-hydroxysubstituted chalcones to flavanones using silica supported-BiCl3 under dry conditions
Naseem Ahmed,Wajid Husain Ansari +1 more
TL;DR: In this paper, the isomerization of 2'-hydroxychalcones to their corresponding flavanones, in good to excellent yield using silica supported-Bi(III) chloride as a catalyst under dry conditions at 70-80°C was reported.
