Useful:

• Chemical Classes: Other Classes -> Organic Acids
• Canonical SMILES: CC=CC=CC(=O)O
• Isomeric SMILES: C/C=C/C=C/C(=O)O
• Inhalation Risk: No indication can be given about the rate at which a harmful concentration of this substance in the air is reached on evaporation at 20 °C.
• Effects of Short Term Exposure: The substance is irritating to the eyes, skin and respiratory tract.
• Effects of Long Term Exposure: Repeated or prolonged contact may cause skin sensitization.
• Natural Origin and Synthesis: Sorbic acid (SA), also known as 2,4-hexadienoic acid, is a natural organic compound derived from the berries of the mountain rowan tree. Despite its natural origin, sorbic acid has been predominantly produced by chemical synthesis to meet the high demand for use as a preservative in food and wine since the 1930s.
• Application as a Preservative: Sorbic acid and its salt, sorbate, have been used as food preservatives since the 1940s to prevent spoilage caused by yeast, fungi, molds, and some bacteria. It can be directly added to food products, sprayed onto surfaces, sprinkled in powder form, dipped into sorbate solutions, or incorporated into packaging materials.
• Safety and Allergies: Sorbic acid is generally regarded as safe and nontoxic as a preservative but may cause allergic reactions or intolerance, particularly in large amounts.
• Functional Properties: Besides its use as a food preservative, sorbic acid is employed as a mold and yeast inhibitor, fungistatic agent, and alkyd coating to improve the gloss and milling characteristics of cold rubber. Its salts are utilized when greater water solubility is required.
• Regulatory Status: Sorbic acid and its salts (potassium and calcium) are classified as food preservatives (E 200, E 202, E 203) in Europe and are widely applied to extend the shelf life of food products.
• Stability and Processing: Sorbic acid is stable when stored at room temperature for extended periods but undergoes autoxidation in aqueous solutions and foods, leading to the formation of carbonyls and other compounds.; Heat treatment during processing does not significantly affect its stability or degradation.
• Industrial Applications: Sorbic acid and its potassium salt serve as alternatives to parabens in the food and pharmaceutical industries, where they are widely used for antimicrobial preservation in various formulations, including aqueous solutions, emulsions, suspensions, gels, and ointments, typically in concentrations ranging from 0.1% to 0.2%.

Vinyl imidates in cycloaddition reactions: Synthesis of (±)-alloyohimbane

10.1016/S0040-4039(00)01093-5

The study focuses on the synthesis of (+)-alloyohimbane, a yohimbine alkaloid, using the intramolecular Diels-Alder reaction of N-acylvinyl imidates as a key methodology. This approach provides a rapid entry into cis-fused hexahydroisoquinolones, which are essential for constructing the DE rings of yohimbine alkaloids. The chemicals used in the study include sorbic acid, LDA (lithium diisopropylamide), acid chloride, 2-ethoxy-1-aza-1,3-butadiene, benzene, NaBH3CNBH3 (sodium cyanoborohydride), TFA (trifluoroacetic acid), and various other reagents for the synthesis and transformation of intermediates. These chemicals serve to deconjugate sorbic acid, form the Diels-Alder precursor, effect the cycloaddition to form the cycloaddduct, and subsequently reduce and modify the product to afford the target lactam and ultimately (+)-alloyohimbane. The study also developed a radical-based strategy for synthesizing indoline electrophiles from o-bromoaniline derivatives, which are crucial for the synthesis of substituted indolines and the completion of the alkaloid structure.
