Nitrogen Attached Indirectly To The Bicyclo Ring System By Nonionic Bonding Patents (Class 549/440)
  • Patent number: 10308588
    Abstract: A mild and efficient synthesis of primary amines and amides from aldehydes or ketones using a heterogeneous metal catalyst and amine donor is disclosed. The initial heterogeneous metal-catalyzed reaction between the carbonyl and the amine donor components is followed by the addition of a suitable acylating agent component in one-pot, thus providing a catalytic one-pot three-component synthesis of amides. Integration of enzyme catalysis allows for eco-friendly one-pot co-catalytic synthesis of amides from aldehyde and ketone substrates, respectively. The process can be applied to asymmetric synthesis or to the co-catalytic one-pot three-component synthesis of capsaicin and its analogues from vanillin or vanillyl alcohol. A co-catalytic reductive amination/dynamic kinetic resolution (dkr) relay sequence for the asymmetric synthesis of optically active amides from ketones is disclosed.

  • Patent number: 6255528
    Abstract: Fluorine-containing phenethylamines are obtained in an advantageous manner by reacting fluorine-containing bromobenzenes with acrylamide in the presence of a palladium catalyst, hydrogenating the resulting arylacrylamides catalytically and then rearranging the arylamides obtained. The invention also embraces novel arylacrylamides and novel arylamides.

  • Patent number: 6232475
    Abstract: The present invention relates to a process for preparing fluorine-containing phenethylamines which is characterized in that, in a first step, a substituted bromobenzene is reacted with an N-vinylimide in the presence of a palladium catalyst, in a second step, the resulting substituted &bgr;-iminovinylbenzene is hydrogenated catalytically and in a third step, the substituted &bgr;-iminovinylbenzene obtained in the second step is cleaved. This process also provides access to novel &bgr;-iminovinyl- and &bgr;-iminoethylbenzenes.

  • Patent number: 6162810
    Abstract: A new family of inadone and tetralone tubulin-binding compounds (TBs) is disclosed. Unlike classical TBs, which inhibit mitosis among affected dividing cells, the TBs of the invention possess two unique properties: (1) they induce apoptosis among stationary phase (non-dividing) malignant cells, yet do not impair the viability of normal nonproliferating cells; and, (2) they affect cells which have acquired MDR more powerfully than they affect cells without MDR. Thus, the TBs of the invention provide means to target malignant cells for chemotherapy, even after previous therapies have failed, without affecting normal cells and tissues in the host.
