Abstract
![]()
An
iridium-catalyzed reductive generation of both stabilized and
unstabilized azomethine ylides and their application to functionalized
pyrrolidine synthesis via [3 + 2] dipolar cycloaddition reactions
is described. Proceeding under mild reaction conditions from both
amide and lactam precursors possessing a suitably positioned electron-withdrawing
or a trimethylsilyl group, using 1 mol% Vaska’s complex [IrCl(CO)(PPh3)2] and tetramethyldisiloxane (TMDS) as a terminal
reductant, a broad range of (un)stabilized azomethine ylides were
accessible. Subsequent regio- and diastereoselective, inter- and intramolecular
dipolar cycloaddition reactions with variously substituted electron-deficient
alkenes enabled ready and efficient access to structurally complex
pyrrolidine architectures. Density functional theory (DFT) calculations
of the dipolar cycloaddition reactions uncovered an intimate balance
between asynchronicity and interaction energies of transition structures,
which ultimately control the unusual selectivities observed in certain
cases.
