Let¡¯s face it, organic chemistry can seem difficult to learn. Especially from a beginner¡¯s point of view. Like 521284-21-9, Name is (R)-2-((4-Nitrophenethyl)amino)-1-phenylethanol hydrochloride. In a document, author is Yuan, Ding, introducing its new discovery. HPLC of Formula: C16H19ClN2O3.
New efficient synthesis of isoquinoline-1,3(2H,4H)-diones and isoindolin-1-ones via sequential Ugi/cyclization reaction
A new efficient synthesis of isoquinoline-1,3(2H,4H)-diones or isoindolin-1-ones via sequential Ugi-4CR or Ugi-3CR/cyclization reaction was developed. alpha-Acylamino amides 5, obtained from Ugi-4CR of methyl 2-formylbenzoate, amines, isocyanates and acids, cyclized to give isoquinoline-1,3(2H,4H)-diones 6 in good yields in the presence of catalytic amount of sodium ethoxide. Ugi-3CR of methyl 2-formylbenzoate, amines and isocyanates in the presence of catalytic amount of H3PO4 produced isoindolin-1-ones 7 directly in one-pot fashion. (C) 2015 Elsevier Ltd.
