ZUR 1,3-THIAZIN-RINGKONTRAKTION: NEUE ASPEKTE DURCH 6-DONORSUBSTITUENTEN

Spitzner, Roland,Schroth, Werner

, p. 3971 - 3974 (2007/10/02)

The reaction of 6-morpholino- and 6-phenylthio-6H-1,3-thiazines with BuLi at low temperature manifests striking differences to the behaviour of 2,4,6-triaryl species: Ring contraction to the pyrrol ring system involves predominantly S-transfer into exocyclic position instead of immediate S-extrusion.The results are discussed in relation to ?-donor effects by 6-heterosubstituents.
