New Chiral Bicyclic Pyrrolidine Block for Nirmatrelvir and Its Analogues
(1R,5S)-2-Ethoxy-6,6-dimethyl-3-azabicyclo[3.1.0]hex-2-ene easily available from (+)-3-carene has been proposed as a key building block for the synthesis of Nirmatrelvir and related compounds. It has been obtained by enol ethylation of (1R,5S)-6,6-dimethyl-3-azabicyclo[3.1.0]hexan-2-one with triethyloxonium tetrafluoroborate.
