- Titanium tetrachloride promoted cyclodehydration of aryloxyketones: Facile synthesis of benzofurans and naphthofurans with high regioselectivity
-
An efficient and facile method for the synthesis of a broad series of benzofurans and naphthofurans is described. The direct intramolecular cyclodehydration of aryloxyketones in the presence of titanium tetrachloride affords the corresponding benzofurans and naphthofurans with good regioselectivity and yields.

- 6-Aryloxy-2-oxo-1-aza-4-oxa (or thia)-spiro[4,5] decanes
-
6-Aryloxy-2-oxo-1-aza-4-oxa(or thia)-spiro [4,5]decane compounds. These compounds are represented by the formula: STR1 in which A stands for an oxygen or sulfur heteroatom; R1 and R2 are each H, lower alkyl or aryl such as phenyl; X is H, a halogen atom such as chlorine or fluorine or a lower alkyl. Compounds according to the invention are useful as stimulating agents for vigilance, as psycho-stimulators and genesic stimulators.
