Rueping, Magnus; Sugiono, Erli; Merino, Estibaliz published the artcile< Asymmetric organocatalysis: an efficient enantioselective access to benzopyrans and chromenes>, COA of Formula: C9H7BrO, the main research area is unsaturated aldehyde cycloalkanedione chiral diaryl prolinol ether; asym addition heterocyclization hydroxychromenone stereoselective preparation reduction oxidation aromatization; lactone oxadecalinone benzopyran stereoselective preparation; addition heterocyclization asym catalyst chiral diaryl prolinol ether.
Valuable, biol. active chromenones such as those depicted were synthesized based on a diaryl prolinol ether catalyzed, enantioselective reaction of diketones with α,β-unsaturated aldehydes. In these efficient addition-acetalization cascade reactions, diverse aliphatic and aromatic α,β-unsaturated aldehydes, as well as various diketones, can be successfully applied and the 2-hydroxychromenones can be isolated in good yields and with excellent enantioselectivities.
Chemistry – A European Journal published new progress about Acetalization catalysts (stereoselective). 3893-18-3 belongs to class bromides-buliding-blocks, and the molecular formula is C9H7BrO, COA of Formula: C9H7BrO.
