Synthesis method for (2-chloro-5-iodophenyl)(4-fluorophenyl)ketone

The invention discloses a synthesis method for (2-chloro-5-iodophenyl)(4-fluorophenyl)ketone. According to the method, with cheap o-chlorobenzoic acid as a starting material, (2-chloro-5-iodophenyl)(4-fluorophenyl)ketone is obtained by nitration, Friedel-Crafts acylation and reduction and finally by Sandmeyer reaction for iodination. The materials used by the method are cheap and easy to obtain, and the method adopting Sandmeyer reaction for iodination can increase the iodine utilization rate, and has the characteristics of simplicity in operation, high yield, high purity and suitability for industrialized production. (The chemical formula is shown in the specification).

PROCESS FOR THE PREPARATION OF 6-(PERFLUOROALKYL)URACIL COMPOUNDS FROM CARBAMATE COMPOUNDS

An improved process for the preparation of 6-(perfluoroalkyl)uracil compounds having structural formula (I) from carbamate compounds having structural formula (II).

Synthesis and antitumor activity of novel benzophenone derivatives

Novel benzophenone derivatives were synthesized and screened for cytotoxic and antitumor activity. Friedel-Crafts condensation was employed to construct the benzophenone skeleton. Among the compounds synthesized, morpholino and thiomorpholino benzophenones 3a-d exhibited potent cytotoxic activity against P388 murine leukemia and PC-6 human lung carcinoma cells in vitro, and compounds 3a, 3c, and 3j, when administered intraperitoneally, showed significant antitumor activity against the malignant ascites caused by intraperitoneal inoculation of P388 cells in mice.

(Benzoylphenyl)piperidines: A new class of immunomodulators

A series of (benzoylphenyl)piperidines has been synthesized and evaluated for activity as immunomodulators. Several of these compounds show good activity in primary screening on the basis of the lymphocytes mitogenic response to Con A, PHA, and PWM. A chloro group in position 4 of the benzoyl moiety as well as an amino group (or a carbamate derivative) para to the piperidine nucleus seems to be essential for activity. The depicted compounds may be considered as the first examples of a new series of immunomodulators.
