Enantioselective Construction of Pyrimidine‐Fused Diazepinone Derivatives Bearing a Tertiary Stereogenic Center Enabled by Iridium‐Catalysed Intramolecular Allylic Substitution. Issue 13 (8th June 2021) - Jiang, Xiaoding
Abstract: The iridium‐catalysed enantioselective intramolecular allylic substitution of pyrimidine‐tethered allylic carbonates was developed. A wide range of chiral pyrimidine‐fused diazepinone derivatives were successfully constructed in 88–96% yields with 85–99% ees. This work further highlights the power of chiral‐bridged biphenyl phosphoramidites in asymmetric synthesis. Abstract :
