Usage

Description

1-(2-Furyl)-2-butanone, commonly known as furaneol, is a natural organic compound that contributes to the sweet, caramel-like aroma and flavor found in various fruits such as strawberries, tomatoes, and pineapples. It is produced during the Maillard reaction, which occurs between amino acids and reducing sugars during the heating or cooking process. As a volatile organic compound, furaneol is considered safe for consumption in small amounts, but excessive exposure may cause respiratory irritation and allergies.

Uses

Used in Food Industry:
1-(2-Furyl)-2-butanone is used as a flavor enhancer for its sweet, caramel-like aroma and flavor, adding to the appeal of food products such as candy, baked goods, and beverages.
Used in Fragrance Industry:
1-(2-Furyl)-2-butanone is used as a component in the creation of artificial fragrances due to its pleasant and distinctive scent, which can be incorporated into perfumes, cosmetics, and other scented products.
Used in Chemical Research:
1-(2-Furyl)-2-butanone serves as a valuable compound in chemical research and development, particularly in the study of the Maillard reaction and the development of new flavor and fragrance compounds.

Chemo- and Regioselective Asymmetric Friedel-Crafts Reaction of Furans and Thiophenes with α,β-Unsaturated Aldehydes through Dual Activation

A highly chemo- and regioselective Friedel-Crafts alkylation reaction of furans and thiophenes has been developed, which relies on the activation from the remote conjugated Mukaiyama silyl enol ether motif. Excellent enantioslectivity is generally obtained in reactions with α,β-unsaturated aldehydes under the well-established iminium ion catalysis of a chiral secondary amine.

GENERAL RELATIONSHIPS IN THE OPENING OF THE OXIRANE RING DURING CLEAVAGE OF GLYCIDIC ACIDS

By investigation of the decarboxylation of 2,3-epoxy derivatives of acids with various structures it was shown that contrary to the existing theory about the essential opening of the β (C-O) bond in the oxirane ring there are many structural types of 2,3-epoxypropionic acids, in which opening of the α (C-O) bond in the oxirane ring occurs during decarboxylation.It was also shown that these two possible reaction paths can also arise during the decarboxylation of one 2,3-epoxypropionic acid.On the basis of the obtained data a general relationship is developed for theopening of the oxirane ring during the decarboxylation of 2,3-epoxypropionic acids with any structure, and this makes it possible to predict the structure of the obtained carbonyl compound.
