# How many stereogenic centers exist in the atropine?

I'm pretty sure that both C bonded to N are stereogenic centers. I don't know about the others, any help? Is this correct?

• I think there is only one chiral center in atropine. Jul 14 at 16:54
• @Curt F.: The ring is symmetric so all three carbon centers shown in are not chiral. The sole chiral center is the $\alpha$-carbon to carbonyl group. Jul 14 at 17:01
• Hi, actually I meant stereogenic center, I don't know if it's different from the definition of chiral center. Jul 14 at 20:34

In this question you can look at the IUPAC definition of the chiral center. According to the definition, carbons that are attached to nitrogen are chiral centers — they have 4 different chemical groups attached to them. The $$\alpha$$-carbon to the ester group is also a chiral center. However, the third carbon (from top to bottom) that you circled is not a chiral center because two groups from the cycle are identical.
