An effective synthesis of 1,3-oxathiolanes

2-Alkyl-or 2,2-dialkyl-1,3-oxathiolanes can be effectively prepared from aldehydes or ketones and 2-mercaptoethanol, with triisopropylsilyl triflate as a catalyst. The reaction is over within minutes and, despite the fact that water is nor removed during the reaction, the yields of products are high.

ACTIVITY OF 1-OXA-3-THIACYCLOALKANES AND 2-ALKYLTHIOOXACYCLANES IN FREE-RADICAL ISOMERIZATION

It was established that radical isomerization to alkyl esters of thiocarboxylic acids, initiated by tert-butyl peroxide at 130-150 deg C, is a common reaction for five-, six- and seven-membered 1-oxa-3-thiacycloalkanes and 2-alkylthiooxacycloalkanes.Under analogous conditions 2-diethylaminotetrahydropyran isomerizes to N,N-diethylvaleramide.The relation between the structure and the reactivity of 1-oxa-3-thiacycloalkanes and 2-alkylthiooxacycloalkanes in free-radical isomerisation was studied by the method of competing reactions.Depending on the ring size, the activity of the 1-oxa-3-thiacycloalkanes increases in the order : 1,3-oxathianes 1,3-oxathiolanes 1,3-oxathiepanes.

Oxathiane and oxathiolane derivatives as perfuming agents

1,3-Oxathiane and 1,3-oxathiolane derivatives, some which are new, are disclosed as being useful as perfuming and flavoring agents for the preparation of perfumes and perfumed articles and for the manufacture of artificial flavors, flavored foodstuffs, animal feeds, beverages, pharmaceutical preparations and tobacco products.

Six membered heterocyclic oxathio compounds

One or more five or six membered oxathio heterocyclic compounds having one sulfur atom and one oxygen atom, such as an oxathiolane or an oxathiane, is used to alter, modify or enhance the flavor or aroma of a foodstuff, chewing gum or medicinal product. A
