| Amin-carbamoyl-10B-boran, Darstellung und biologische Eigenschaften Amine-carbamoyl-dihydro-10B-borane, Preparation, and Biological Properties  | | | | Abstract
| The chemical section deals with the synthesis of sodiumcyano-"'B-borhydride (3) from l0B-boric acid trimethyl ester (1) via sodium-inB-borhydride (2). By converting 3 with trimethylammonium chloride, trimethylamine-cyano-10B-borane (4) is formed which, via nitrilium tetrafluoroborate 5, is transformed by water to Trimethylamine-carboxy-dihydro-luB-borane (6). Trimethylamine-ethoxycarbonyl-dihydro-l()B-borane (8b) and amine-carbamoyl-dihydro-"'B-borane (8c) can be synthesized from the imidazolid 8a. In the biological section an orientation to the toxicity and the tumor affinity of the compounds 6, 7. and 8c are described. Further the possibility is shown by achieving a maximal concentration of 10B-boron in the tumor whilst at the same time retaining as low a concentration of 1()B-Boron as possible in the surrounding tissue. | | | |

| Synthesis of l,2-Dipalmitoyloxypropyl-3-(2-ammoniumethyl) Phosphinate | | | | Abstract
| The total synthesis of l,2-dipalmitoyloxypropyl-3-(2-ammoniumethyl) phosphinate, the phos-phino-analog of phosphatidyl ethanolamine is described. The phosphinate analog of phosphatidyl ethanolamine has been prepared by an Arbusov type of reaction between a diacyl-glycerol bromohydrin and 2-bromo-ethylphosphonic acid dimethyl ester for 48 h at 178 °C, followed by a reaction with aq. ammonia to yield the final product. The product was characterized by elemental analysis, phosphono-phosphorus determinations and IR spectroscopy. | | | |
