Microwave-Assisted Wolff Rearrangement of Cyclic 2-Diazo-1,3-Diketones: An Eco-compatible Route to α-Carbonylated Cycloalkanones
摘要:
The microwave-assisted Wolff rearrangement of cyclic 2-diazo-1.3-diketones performed in the presence of a stoichiometric amount of alcohol, amine, or thiol is an efficient, user, and environmentally friendly synthetic protocol for the synthesis of alpha-carbonylated cycloalkanones. This approach proves superior to existing protocols in scope and eco-compatibility.
The combination of aminocatalysis with N-heterocyclic carbene catalysis has been expanded to a switchable dual catalytic system, which allowed a direct enantioselective entry to bridged bicyclo[3.n.1] ring systems and the...
