Functionalization of 4,5-dihydrobenzo[g]indazoles using magnesium- or zinc-heterocyclic intermediates
4,5-Dihydrobenzo[g]indazoles were efficiently metallated using hindered Mg- and Zn-TMP amides. Trapping of the resulting organometallic reagents with various electrophiles furnished novel C3-substituted 4,5-dihydrobenzo[g] indazoles.
