Useful:

• Canonical SMILES: CCOC(=O)C=CC=CC
• Isomeric SMILES: CCOC(=O)/C=C/C=C/C
• Uses: The addition of chlorine and bromine to ethyl sorbate (la) gave 1, 2-and 1, a-dihalo products derived from attack of the halogen. Chlorination of la under ionic conditions proceeds through a tightly bridged chloronium ion intermediate. Ethyl Sorbate is a synthetic flavoring agent that is a moderately sta- ble, light yellow liquid of fruity odor. it should be stored in glass or tin containers. it is used in flavors such as pineapple, papaya, and passion fruit with applications in ice cream, beverages, candy, and baked goods at 6–18 ppm. it is also termed ethyl-2,4-hexadienoate.

Enantioselective syntheses of cryptocarya triacetate, Cryptocaryolone, and cryptocaryolone diacetate

10.1021/ol0345529

The research focuses on the enantioselective syntheses of three natural products derived from Cryptocarya latifolia, a South African plant known for its medicinal properties. The study aims to establish the absolute and relative stereochemistries of cryptocarya triacetate, cryptocaryolone, and cryptocaryolone diacetate, and to develop efficient synthetic routes to these compounds. The research concludes that a highly enantio- and diastereoselective route has been successfully implemented, utilizing asymmetric catalysis and efficient diastereoselective reactions. Key chemicals used in the process include ethyl sorbate, Sharpless dihydroxylation reagents, palladium catalysts, and Grubbs' catalyst for cross-metathesis reactions.
