An efficient strategy for the formation of alkenyl-functionalized spirocarbocyclic scaffolds from al-kyne-containing phenol-based biaryls via sequential iodine-
Polycyclic fused quinazolinones with anti-malarial activity were synthesized through tert-butyl hydro-peroxide(TBHP)-mediated oxidative decarboxylative cyclizat
We have developed an efficient Pd-catalyzed directed C-H bromination protocol,in which dimethyl sulfoxide(DMSO)is employed as oxidant with hydrobromic acid aque
