Synthetic studies on carbapenem antibiotics from penicillins v. a stereospecific preparation of 4 allylazetidinones


, : Synthetic studies on carbapenem antibiotics from penicillins v. a stereospecific preparation of 4 allylazetidinones. Heterocycles (Tokyo) 23(8): 1889-1892

A stereospecific preparation of chiral 4-allylazetidinones _3, key intermediates for the synthesis of the carbapenem antibiotics, has been achieved in good yields by reaction of 4-acetoxyazetidinones _2 with allylsilanes in the presence of TMSOTf.

The chemical composition of the soil solution at a depth of 50-80 cm was studied for 20 months, starting 13 months after windthrows in 13 Picea abies ecosystems in Germany. The results, presented in detail, indicate high or very high nitrate condi...

It is shown that the well-known region of recombination values for which D = 0 is locally stable does not preclude the local stability of an equilibrium with D not equal 0....
