Synthesis of Marine Diterpene Isocyanide (−)-Kalihinol Y and Diterpene Isothiocyanate (−)-10-Epi-kalihinol I

The authors described the first synthesis of diterpene isocyanide (-)-kalihinol Y and diterpene isothiocyanate (-)-10-epi-kalihinol I from synthetic intermediates of kalihinol A. The absolute structures of these compounds were confirmed by these syntheses.
