In connexion with studies of cyclic polymerisation the allyl derivatives of ethylenediamine and diethylenetriamine have been prepared, and the new compounds have been characterised. The mixture of triamines obtained by direct allylation of diethylenetriamine has been separated by ion-exchange chromatography. The order of elution agrees with the calculated basic strengths of the compounds, and their

carried out for the Rh-Acy-POL catalyst. Both the activity and selectivity could be maintained for at least seven reaction runs and without metal leaching during the reaction cycles. We have also studied the liquid-phase hydrogenation reaction of various styrene m-substituted derivatives. The Rh-Acy-POL catalyst exhibits excellent catalytic activity for hydrogenation of the substrates and only vinyl-group

Abstract A novel type of aromatic diamines (20 - 28) containing both oxygen and nitrogendonors were synthesized by Raney nickel-catalyzed hydrazine or amalgamated aluminum reduction of the corresponding nitro-compounds (3,12 - 19), which were prepared by condensation of N-substituted nitrogen mustards (4 - 11) with 2-nitrophenol in the presence of potassium carbonate in DMF at 80 °C for 6 h.
This invention relates to novel isoxazolines and isoxazoles of formula (I):

or a pharmaceutically acceptable salt or prodrug form thereof. The invention relates to novel isoxazolines which are useful as antagonists of the platelet glycoprotein IIb/IIIa fibrinogen receptor complex, to pharmaceutical compositions containing such compounds, processes for preparing such compounds, and to methods of using these compounds, alone or in combination with other therapeutic agents, for the inhibition of platelet aggregation, as thrombolytics, and/or for the treatment of thromboembolic disorders.
