DABCO-catalyzed [2+2] cycloaddition reactions of allenoates and trifluoromethylketones: synthesis of 2-alkyleneoxetanes
摘要:
DABCO was found to be an efficient catalyst for the formal [2+2] cycloaddition reaction of allenoates and trifluoromethylketones (Paterno-Buchi reaction) to give the corresponding 2-alkyleneoxetanes in good yields with good diastereoselectivities. (C) 2011 Elsevier Ltd. All rights reserved.
