Structure-Odor Correlations in Homologous Series of Mercapto Furans and Mercapto Thiophenes Synthesized by Changing the Structural Motifs of the Key Coffee Odorant Furan-2-ylmethanethiol

Furan-2-ylmethanethiol (2-furfurylthiol; 2-FFT, 1) is long-known as a key odorant in roast and ground coffee and was also previously identified in a wide range of thermally treated foods such as meat, bread, and roasted sesame seeds. Its unique coffee-like odor quality elicited at very low concentrations, and the fact that only a very few compounds showing a similar structure have previously been described in foods make 1 a suitable candidate for structure-odor activity studies. To gain insight into the structural features needed to evoke a coffee-like odor at low concentrations, 46 heterocyclic mercaptans and thio ethers were synthesized, 32 of them for the first time, and their odor qualities and odor thresholds were determined. A movement of the mercapto group to the 3-position kept the coffee-like aroma but led to an increase in odor threshold. A separation of the thiol group from the furan ring by an elongation of the carbon side chain caused a loss of the coffee-like odor and also led to an increase in odor thresholds, especially for ω-(furan-2-yl)alkane-1-thiols with six or seven carbon atoms in the side chain. A displacement of the furan ring by a thiophene ring had no significant influence on the odor properties of most of the compounds studied, but the newly synthesized longer-chain 1-(furan-2-yl)- and 1-(thiophene-2-yl)alkane-1-thiols elicited interesting passion fruit-like scents. In total, only 4 out of the 46 compounds also showed a coffee-like odor quality like 1, but none showed a lower odor threshold. Besides the odor attributes, also retention indices, mass spectra, and NMR data of the synthesized compounds were elaborated, which are helpful in possible future identification of these compounds in trace levels in foods or other materials.

Intramolecular Cycloadditions. Studies of Relative Asymmetric Induction

Treatment of both the E and Z isomers of alkoxyallylic sulfones 20a and 20b with TiCl4 results in the formation of 4 + 3 cycloadducts by intramolecular cycloaddition.The distribution of diastereomers is different from each isomer of educt.This suggests that cycloaddition occurs faster than any isomerization process of the intermediate allylic cations.Both the E and Z isomers of 20c lead to the same 4 + 3 cycloadduct with essentially complete diastereoselectivity.Inherently high simple diastereoselection and a strong conformational bias in the allylic cation intermediates for both isomers account for this selectivity.The importance of allylic cation stereochemistry in these reactions is underscored by the cyclization of 20d.The Z isomer give only 4 + 3 cycloadducts with excellent relative but poor simple diastereoselection, suggestive of a concerted reaction.The E isomer give a cycloadduct, enol ether 60, as the major cycloadduct as well as 4 + 3 cycloadducts and chloride-trapping product 61.This result is indicative of a stepwise reaction.The data reflect the importance of allylic cation stereochemistry in the regiochemical and stereochemical outcomes of intramolecular 4 + 2 cycloaddition reactions.
