Unprecedented formation of Δ2-isoxazoline and/or 1-nitroso-pyrazoline from α-bromoketone oximes and diazo compounds
摘要:
Reaction of alpha-bromoketone oximes with diazo compounds in the presence of a metal catalyst and base led to the unprecedented formation of two types of rings: Delta(2)-isoxazolines and 1-nitrosopyrazolines. (C) 2008 Elsevier Ltd. All rights reserved.
