Regioselective palladium (O) catalyzed azidation and amination of 1-alkenylcyclpropyl esters: a new route to 2,3-methanoamino acids.
摘要:
Palladium (0) catalyzed azidation of 1-alkenylcyclopropyl esters provides regioselectively 1-azido-1-alkenyl cyclopropanes, convenient precursors of 2,3-methanoamino acids. On the other hand, amination occurred exclusively on the less substituted allylic end, providing strained 2-cyclopropylideneethylamine derivatives.
