title: Two new monoterpenoid α-pyrones from a fungus Nectria sp. HLS206 associated with the marine sponge Gelliodes carnosa.
abstract: Two new monoterpenoid α-pyrones, named nectriapyrones C and D (1 and 2), along with a known α-pyrone (nectriapyrone, 3) were isolated from a marine-derived fungus Nectria sp. HLS206 associated with the marine sponge Gelliodes carnosa collected from the South China Sea. Their structures were determined on the basis of 1D NMR, 2D NMR, HR-ESI-MS methods.
