Chiral Bis(imidazolidine)iodobenzene (I-Bidine) Organocatalyst for Thiochromane Synthesis Using an Asymmetric Michael/Henry Reaction
Bis(imidazolidine)iodobenzene (I-Bidine) was designed as an organocatalyst based on previously reported imidazolidine- or oxazolidine-containing chiral metal catalysts. I-Bidine showed catalytic activity for the Michael/Henry reaction of thiosalicyl aldeh
Diversity-oriented asymmetric catalysis (DOAC): Stereochemically divergent synthesis of thiochromanes using an imidazoline-aminophenol-nickel-catalyzed michael/henry reaction
The (S,S)-diphenylethylenediamine-derived imidazoline-aminophenol-Ni complex catalyzed tandem asymmetric Michael/Henry reaction of 2-mercaptobenzaldehydes with β-nitrostyrenes to give the corresponding (2S,3R,4R)-2-aryl-3-nitrothiochroman-4-ols in up to 9
