✦ Synopsis
We have reported, in the preceding communication (I), that the thermal rearrangement of methallyl 3quinolyl sulfide (I) affords 2,2-dimethyl-1,2-dihydrothieno12,3-clquinoline (II) and 2-methyl-2,3-

We report a novel substituent effect in the reaction of allylic triehtoroacetimidates with N-halosuccinimides. Reaction ofE allylic trichloroacetimidates bearing phosphonate or cyano substituents with N-BS in CHCl3 results in a [3.3] sigmatropic rearrangement. In contrast, the Z allylic phosphonate
## Abstract magnified image A number of new 4‐aryloxymethylene‐2,3,5‐trihydrothiopyrano[3,2‐__b__]indoles are regioselectively synthesized in 78‐84% yield by the __thio__‐Claisen rearrangement of 3‐(4′‐aryloxybut‐2′‐ynylthio)indoles. The endocyclic double bonded products are isolated by introducin
