RESUMO
On June 29, 2000, the Council of the School of Veterinary Medicine Hannover (TiHo) passed a new fundamental order. Upon termination of the current terms of office of the rector and the chancellor in September and at the end of the year 2001, respectively, a school management will be established with a longer term of office and a new type of School Council. However, the new fundamental order must still be approved by the Lower Saxony Ministry of Science and Culture. This change has been made necessary by radical restructuring affecting all universities in Lower Saxony: the transformation to a state enterprise with the concomitant introduction of a global budget demands full-time management. This is a step of historical significance, for this change in the fundamental order puts an end to a tradition of 87 years at the School of Veterinary Medicine Hannover under a constitutional rectorate. The following essay describes the most important changes and explains their necessity.

(Z)-Tetracos-5-enoic acid is a key intermediate in the biosynthesis of myocobacterial mycolic acids. Recently the methyl ester of its cyclopropene analogue, methyl 4-(2-octadecylcyclopropen-1- yl)butanoate, was shown to act as an inhibitor of mycolic acid biosynthesis. The related analogues methyl 5-(2-octadecylcyclopropen-1-yl)pentanoate and methyl 3-(2-octadecylcyclopropen-1-yl)propanoate have been synthesized, as well as the related cyclopropane esters methyl (Z)-4-(2-octadecylcyclopropan-1-yl)butanoate and methyl (Z)-5-(2-octadecylcyclopropan-1-yl)pentanoate. The synthesis of methyl 3-(2-octadecylcyclopropen-1-yl)propanoate involved protection of the cyclopropene ring by iodination to allow oxidation of an alcohol to a carboxylic acid; the diiodocyclopropane was deprotected by a new mild procedure using activated zinc.
