    Description / Table of Contents: Diastereoselectivity in the Boranate Reduction of α-Triazolyl KetonesThe influence of TiCl4 on the formation of diastereomers during the boranate reduction of α-triazolyl ketones 1 is investigated. Without TiCl4 the formation of diastereomer 3 with the hydroxy and triazole goup syn to each other is preferred. However, in the presence of TiCl4 the diastereomer 2 with anti position of hydroxy and triazole group is formed with high selectivity.
    Notes: Der Einfluß von TiCl4 auf das Diastereomerenverhältnis bei der Boranatreduktin von α-Triazolylketonen 1 wird untersucht. Während ohne TiCl4 überwiegend das Diastereomere 3 mit syn-Anordnung von Triazol- und Hydroxyl-Gruppe gebildet wird, dirigiert TiCl4 die Reduktion mit hoher Selektivität zum Diastereomeren 2 mit anti-Anordnung von Triazol- und Hydroxyl-Gruppe.
