Sulfones of 7-silyl- and 7-germylcephalosporanates
Abstract
7-Silyl- and 7-germylcephalosporanates in the form of a mixture of 7α and 7β stereoisomers were prepared by the interaction of hydrosilanes and a hydrogermane* with sulfones of tert-butyl esters of 7-diazocephalosporanic acid and 7-diazodesacetoxycephalosporanic acid in the presence of rhodium diacetate. Some of the synthesized substances manifest cytotoxic effects in relation to tumor cells in vitro, and also inhibit the catalytic activity of the enzyme elastase.
