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.
