Regio- and stereoselective 1,2 Wagner-Meerwein shifts during trifluoroacetic acid catalyzed isomerization of unsymmetrically substituted tricyclo[3.2.0.02,4]heptanes

Abstract

Die Faktoren, die die Regio‐ und Stereoselektivität bei der TFA‐katalysierten Isomerisierung der Tricycloheptane (VI) bestimmen, und der Mechanismus der Reaktion werden ausführlich untersucht und diskutiert.
