WebThe atoms attached to C5 are C, H, H. There is no difference. To decide between C2 and C5, we must go one atom further out. From C2, C3 has F, C, H. From C5, C4 has C, H, H. C2 is therefore #2, and C5 is #3. If you assign these priorities to the groups, the sequence 1 → 2 → 3 goes in a counterclockwise direction (S). WebJan 12, 2024 · Optically active chiral triptycenes have also been prepared by attaching enantiomerically pure molecule to the triptycene unit. 9 The chiral auxiliary (S)-3,7-dimethyloctyl bromide has been connected to a triptycene moiety to obtain a chiral polymer. 10a Similarly, (R)-(+)-1,1’-bi-2-naphthol has been used in the synthesis of chiral …
