Reaction of Alkynyl Alkoxy Metal (Cr, W) Carbene Complexes with 1,3-Dinitrogen Systems. A Direct Entry to the Pyrimidine Skeleton

The reaction of alkynyl alkoxy metal (Cr, W) carbene complexes with 1,3-dinitrogen systems (amidines, guanidines, ureas) is described. In all cases, the main product obtained corresponds to the cycloadduct whose cyclic structure may be related to a pyrimidinic ring arising from a formal [3 + 3] cycl...

Description
Summary:The reaction of alkynyl alkoxy metal (Cr, W) carbene complexes with 1,3-dinitrogen systems (amidines, guanidines, ureas) is described. In all cases, the main product obtained corresponds to the cycloadduct whose cyclic structure may be related to a pyrimidinic ring arising from a formal [3 + 3] cycloaddition between the metal carbene complexes and the dinitrogen systems.
