The experimentally determined and estimated stereoselectivities (α) for the chiral compounds used in this study

Compound	α (Exp)	α (Est)
(R,S)-verapamil	77	150
(R,S)-atenolol	0.5	0.8
(R,S)-propranolol	3.0	1.4
(RR,SS)-pseudoephedrine	1.5	1.8
(RR,SS)-fenoterol	0.3	0.4
(RS,SR)-fenoterol	0.5	0.7
(R,S)-isoproterenol	1.5	1.4
(R,S)-disopyramide	2.0	1.2
Quinine/quinidine	1.6	1.5
(R,S)/(R,R)-fenoterol	1.1	1.2
(S,R)/(R,R)-fenoterol	0.5	0.9
(R,S)/(S,S)-fenoterol	3.5	2.8
(S,R)/(S,S)-fenoterol	1.7	2.1

For the enantiomeric pairs, the α value is defined as K_i(S)/K_i(R), and for the diastereomeric pairs, the ratios are as presented in the table.
