  Proximity effects in the electron impact mass spectra of aurones and related compounds

  摘要：

  AbstractThe principal ions in the electron impact mass spectra of a series of 6‐methoxyaurones have been shown to be due to four separate reactions associated with proximity effects involving the phenyl group and the coumaran‐one residue. A detailed study with labelled derivatives has been supplemented by a study of the vinylogue 2‐cinnamylidene‐6‐methoxycoumaran‐3‐one and compounds in which the aurone phenyl group has been replaced by α‐naphthyl, β‐naphthyl and 9‐anthryl.

  The synthesis and the biological evaluation of a series of basic ethers of 2-benzyl-3-arylbenzofurans as antitumor agents is described. These compounds bind significantly to the antiestrogen-binding sites but only poorly to the estrogen receptor sites and are cytotoxic to tumor cells. Some of these compounds also significantly inhibited de novo cholesterol biosynthesis in an estrogen receptor negative lymphoma cell line rich in antiestrogen-binding sites.

  one-pot three-component process for the synthesis of derivatives using cycloadition catching azomethineylides in situ created by means of decarboxylative build-up of sarcosine and isatin has been developed in hexyltriphenylphosphonium bromide (HTPB) as an ionic liquid and recyclable solvent in supreme yield without the use of a catalyst under ultrasonic irradiation. This method offers mild reaction conditions
