The resulting chiral 3-hydroxyoxindoles could be used as synthetic precursors for the synthesis of several natural products with a broad spectrum of fascinating biological activities.}, pages = {1638--1646}, title = {Hybrid-Type Squaramide-Fused Amino Alcohol Organocatalysts for Enantioselective Nitro-Aldol Reaction of Nitromethane with Isatins}, year = {2017}, yomi = {セキ, チグサ and オクヤマ, ユウコ and ウワイ, コウジ and トキワ, ミチオ and タケシタ, ミツヒロ and ナカノ, ヒロト} }
