Talk:Α-Pinene

message: The ponderosa pine bark has an odor that resembkes vanilla and butter scotch. The park service claims that the odor is caused by alpha pinene. My knowledge as a pharmacist inclines me to think that alpha pine has a pine odor. I will be grateful for any information.

:alpha-Pinene is a major constituent of turpentine, and it smells rather like that (as you might expect).  I don't think it has a vanilla/butterscotch smell - but smells can be peculiar, depend on concentrations and other constituents, etc.  The main constituent of vanilla is vanillin, an aromatic aldehyde.  Can't help more, I'm afraid! Walkerma 05:28, 12 October 2006 (UTC)

message: The smiles for this entry has 12 carbons but a-pinene has the formula C10H16. The SMILES should be regenerated. --Steinbeck (talk) 13:00, 11 May 2009 (UTC)
replies: text: The SMILES string currently in the article - C\1=C(\[C@@H]2C[C@H](C/1)C2(C)C)C - is correct and has 10 carbons.  -- Ed (Edgar181) 19:40, 14 July 2011 (UTC)

message: As far as I can tell, the Iodine addition in the reaction chart is incorrect. I am almost certain that I2 addition to alpha-pinene results in a diiodinated product.

replies: text: It's quite possible that the product will vary depending on the reaction conditions.  Under some conditions, elimination of hydrogen iodide following the addition of iodine could give the product shown.  -- Ed (Edgar181) 19:44, 14 July 2011 (UTC)
thread_title:  Iodine Addition? 

message: I corrected the ChEBI entry to point to the class alpha-Pinene. The previous entry pointed to (-)-alpha-pinene, which is only one of the two enantiomers discussed here. Ideally, the ChemBox would allow for listing the class CHEBI:36740 and the two enantiomers CHEBI:28660 and CHEBI:28261, like it is done for the CAS numbers. Can anyone enlighten me if we have a mechanism for this?

replies: text: .  Yes, in the infobox template in addition to "| ChEBI =" you can use "| ChEBI1 =" and "| ChEBI2 = " etc.  -- Ed (Edgar181) 13:31, 19 May 2016 (UTC)
