efficient method for the synthesis of 1,2-dihydroisoquinolines. We have synthesized few 1,2-dihydroisoquinolines having different functionality at the C-1, C-3, C-7, and N-2 positions for evaluation against HIV-1 integrase (HIV1-IN) inhibitory activity. A direct nitro-Mannich condensation of o-alkynylaldimines and dual activation of o-alkynyl aldehydes by inexpensive cobalt chloride yielded desired compounds

A highly effective 6-endo dig cyclisation of o-alkynylaldimines to 1,2-dihydroisoquinolines has been described via direct and nitro Mannich condensation using inexpensive and readily available cobalt chloride as catalyst. This strategy provides an effective procedure for the synthesis of substituted 1,2-dihydroisoquinolines derivatives in moderate to high yields. An addition of pronucleophiles, such
