Reactions of Thioketones with Methyl Azidoacetate


Mloston, Grzegorz; Romanski, Jaroslaw; Linden, Anthony; Heimgartner, Heinz (1996). Reactions of Thioketones with Methyl Azidoacetate. Polish Journal of Chemistry, 70(7):880-890.

Abstract

The reaction of methyl azidoacetate with several thiocarbonyl compounds at 80°C leads to imine derivatives of methyl glycinate in yields of about 60%. With 2,2,4,4-tetramethyl-3-thioxocyclobutanone, only 19% of the corresponding glycinate 19 is obtained. The main products in this reaction are the symmetrical dispiro-1,2,4-trithiolane 20 and the dispiro-1,4,2-dithiazolidine 21 (Scheme 6). The structure of the latter was established by X-ray crystallography. A reaction mechanism involving an intermediate thiocarbonyl-S-sulfide and a thiocarbonyl-S-imide is proposed in Scheme 2.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
