Originally posted by nautica I agree, our melting poing is the 200 and that would be the product. A characteristic reaction of phenylpropanoic acid is its cyclization to indanones. No, the anti product is the erythro product.
The middle bar shows the portion of the estimated values within the experimental error range. If so than you can't say anything based on mp. Based on this mp it would be the erythro pairs, which I thought was the syn version of this product. It can also act as an , to keep oil and water mixtures separated. The license term may be renewed upon the agreement of both parties, but no later than thirty 30 days prior to the expiration of the license.

When the side chain is homologated by the , subsequent cyclization affords , derivatives. This compound is used as a sweetener as well to sweeten food and can be found in table top sweeteners.

When you use them you may be asked to supply some personal information. We got melting of the 200 C.
Bromine addition only gives the anti product. Originally it was prepared by reduction with in water and by. Phenylpropanoic acid is also added to food for technological purposes in a wide variety including manufacturing, processing, preparation, treatment, packaging, transportation or storage, and food additives. Does the anti addition not result in the anti product? Draw the structure of 2S, 3R -2,3-dibromo-3-phenylpropanoic acid. It's stuck in the three membered ring bromonium ion, which is quite stable.
Remember that the starting material is trans, make the anti product model and then rotate the bond, you'll get the erythro product. Upper and lower bar line I represents the experimental error range. If you have any questions please feel free to contact us via email at. Nautica You stated earlier that the other option has a mp of 98. We do use information you provide to better serve your needs.
You do get a 1:1 mix of the enantiomers, they have the same melting point. When the side chain is homologated by the , subsequent cyclization affords , derivatives.

Phenylpropanoic acid has a wide variety of uses including cosmetics, food additives, and pharmaceuticals. The ring does not open until the bromide attacks on the opposite face. So we know that it is either the syn or the anti addition.

The alternative to the anti 2S, 3R and 2R, 3S product would be the cis product 2S, 3S + ent. This compound and its enantiomer are known as threo isomers and have a melting point of 93-95 °C. This compound and its enantiomer are known as erythro isomers and have a melting point of 202-204 °C. We may amend this policy at any time by posting a revised version on our website. So we know that it is either the syn or the anti addition.
If so than you can't say anything based on mp. We got melting of the 200 C. I know that when the Br joines, it joins between the 2 carbons which would cause a trigonal planar situation, but when that is broke the bond should be free to rotate???
