a Scale-up synthesis, [a]Reaction conditions: 4aa (1 mmol), ZnBr2 (1.2 mmol) in DCM (10 mL) at room temperature for 12 h, see Supplementary Notes. No further post-processing required; b Synthetic transformations, b-fRelated iso(thio)cyanate compounds (1.2 mmol) were added, and the mixture was stirred at room temperature for 24 h. Isolated yields were given here and ee value was determined by HPLC.
