실험 절차

The nitrogen in the above diazastilbenes and monoazastilbenes may be replaced with other heteroatoms and heterocycles to yield targets as shown in Scheme 71. ##STR91## For instance, 3-styrylthiophene (172) yields a photocyclization product (J. Chem. Soc. C, 2504 (1970) which may be converted by the methods described above to 4H-indeno[1,2-b]thiophene (173). Likewise, 2-styrylthiophene (175) is converted by photocyclization [J. Chem. Soc., 6221 (1965)] to an intermediate that will yield 8H-indeno[2,1-b]thiophene (176). These may then be alkylated by picolyl chloride to yield 4,4-bis(4-pyridinylmethyl)indeno[1,2-b]thiophene (174) and 8,8-bis(4-pyridinylmethyl)indeno[2,1-b]thiophene (177). Also, the furan derivatives are available via this route (Z. Naturfursch., Teil B, 24 (1969).
