    • Details of the X-ray structure analyses of F1, (R,2 pR)- 2a, (1 pR)- 1a, (+)- 1c, and (-)- 4c are compiled in Table 1 in the Supporting Information. It is worth noting that the Flack parameters of (R,2 pR)- 2a and (+)- 1c complexes are better than those of (1 p R)- 1a and (-)- 4c complexes. But as the two last complexes are derived from (R,2 pR)- 2a and (+)- 1c with procedures that maintain the stereochemical information, the absolute stereochemical assignments of (1 pR)- 1a and (-)- 4c are thus confirmed.
