Development of Highly Enantio- and <i>Z</i>‑Selective Grubbs Catalysts via Controllable C–H Bond Activation
Asymmetric olefin metathesis is a powerful strategy for
stereocontrolled
synthesis that allows the formation of chiral elements in conjunction
with carbon–carbon double bonds. Here, we report a new series
of cyclometalated stereogenic-at-Ru catalysts that enable highly efficient
asymmetric ring opening/cross-metathesis (AROCM) and asymmetric ring-closing
metathesis (ARCM) reactions. Single enantiomers of these catalysts
with either right-handed or left-handed configurations at the Ru center
can be easily accessed via highly stereoselective C–H bond
activation-based cyclometalation. Right-handed chiral Ru catalysts
enabled the Z- and enantioselective AROCM of a wide
range of norbornenes and terminal alkenes, generating densely functionalized
cyclopentanes with excellent stereo- and enantioselectivities (99:1 Z/E, up to 99% ee). Left-handed chiral
Ru catalysts enabled the facile ARCM of sterically unhindered, all-terminal
prochiral trienes, which had not been achieved by previous Ru catalysts,
providing simple cyclic ethers and amides with tertiary or quaternary
carbon stereocenters with excellent enantioselectivities (up to 99%
ee)
