Stereoselective synthesis of 2-(α-hydroxyalkyl)benzimidazoles
摘要:
Lithiated oxazolo[3,4-a]benzimidazole 4 reacted with various alkyl halides to give oxazolo[3,4-a]benzimidazoles 5a-d in good yields as single diastereoisomers. (R)-Benzimidazol-2-y1 carbinols 6a-d were obtained upon hydrolysis under acidic conditions of 1H,3H-oxazolo[3,4-a]benzimidazole derivatives. (C) 1998 Elsevier Science Ltd. All rights reserved.
