Abstract: The reactivity of pnictinidenes [2-(DippN=CH)-6-(DippNHCH2)C6H3]E (where E = As (1) or Sb (2)) toward substituted ortho- and para-quinones is reported. The central pnictogen atom is easily oxidized by ortho-quinones closing five-membered EO2C2 ring. The oxidized… read more here.

DOI: 10.1021/acs.orglett.9b01496
Abstract: Distal aminoalkyl-substituted quinones have been efficiently prepared through silver-catalyzed site-selective deconstruction and C-C bond transformation of unstrained N-acylated cyclic amines. This method enjoys mild reaction conditions, high selectivity, a broad scope of substrates, and a… read more here.
