Synthesis of fluorine-containing α-alkyl-α-diazoesters and their utility in enantioselective cyclopropanation
B Bagale, KM Sobie, JD Mighion - Tetrahedron Letters, 2024 - Elsevier
The synthesis and utilization of fluorine-containing α-alkyl-α-diazoesters has been reported.
Access to fluoroalkyl cyclopropanes was achieved utilizing Rh 2 (S-PTTL) 4 as a catalyst
with good yields, enantioselectivities, and diastereoselectivities across a series of styrenes
and α-alkyl-α-diazoesters. This study expands the accessibility of fluorine-containing
building blocks for synthesis.
