- DIHYDRO-CYCLOPENTA-ISOQUINOLINE SULFONAMIDES DERIVATIVES
-
The present invention relates to dihydro‐cyclopenta‐isoquinoline derivatives of formula (I): processes for preparing them, pharmaceutical compositions containing them and their use in treating disorders caused by IgE (such as allergic responses, non‐allergic mast cell responses or certain autoimmune responses), and in particular, disorders caused by the interaction of IgE with the FcεRI receptor.

- Aromatic Spiranes, XIV: Syntheses of 2,2'-Spirobi-(s-hydrindacene) and its precursors
-
The title compound 35 was prepared by catalytic reduction of the diones 29a and 11a. 29a was synthesized by systematic anellation of fivemembered rings to the positions 5,6 and 5',6', resp., of 2,2'-spirobiindane.The preparation of 11a was achieved by Friedel-Crafts cyclisation of bis-(5-indanylmethyl)-malonic acid. s-Hydrindacene-1-one 5a was prepared as a precursor for the synthesis of 11a (see forthcoming publication) and its derivates as models for corresponding anellation and substitution reactions. - Keywords: s-Hydrindacene-1-one and derivates; Mono- and bisanellation; 2,2'-Spirobiindane; 1H-nmr spectra

- Tricyclic aromatic ketones by cycliacylation of carboxylic acid derivatives of indan, tetralin, and benzosuberane
-
The synthesis of a homologous series of new carboxylic acids substituted in the α-position of indan, tetralin, and benzosuberane is accomplished using an efficient general procedure.Cycliacylation of these acids and their corresponding β-isomers produces a complete series of tricyclic aromatic ketones.
