Asymmetric hydrogenation of alkyl(vinyl)thioethers: a promising approach to α-chiral thioethers
摘要:
This paper describes the enantio selective hydrogenation of vinylthioethers. We show that thioether derivatives of maleic esters can be hydrogenated with full conversion and up to 60% ee, and that alpha-thioether cinnamic acids can be hydrogenated in 51% ee with modest conversion.

Aryl substituted thiophenes 3-ols, its dihydro derivatives, 1-oxide and 1,1-dioxide analogs, as well as aryl substituted furans, are 5-lipoxygenase inhibitors useful in the treatment of inflammation and other leukotriene-mediated diseases.
