[edit] Levobupivacaine
Thanks for the heads up. I checked the structure and it does appear to be correct according to PubChem and the IUPAC name function in ChemDraw. The image in the PI is indeed a mirror image, meaning that the bond changes from "pointing out" (as in the PI) to "pointing in" (as in this image) without changing chirality. -Techelf 12:49, 18 May 2006 (UTC)
- The representation of stereochemistry in structural diagrams can be a bit confusing sometimes. The convention is that solid "wedges" point out of the page, and dashed "wedges" point into the page. The "direction" of the wedge indicates the position of the chiral centre – the broad end is the end further away from the chiral centre. For example, morphine has substituents pointing in and out of the page. -Techelf 08:25, 24 May 2006 (UTC)
