NUCLEOPHILIC RING OPENING OF ANNULATED AZIRIDINES IN LIQUID SULFUR DIOXIDE

摘要

The present invention describes the synthesis process of carbamate derivatives (3) and (4), containing halogen, pseudohalogen or thio group,.from benzyl-7-azabicyclo[4.1.0]heptane-7-carboxylate (1) and salts of I or II group metalls, or sulphurous nuclephile, using sulphurdioxide as solvent.
