| Abstract: | The absolute configuration of the decipiene diterpenes has been determined by degradation to 4R-4-(2-methoxy-4-methylphenyl)-pentanoic acid. Photolysis of 1,18-diacetoxy-13-oxodecipi-14-ene proceeds through a novel photochemical reaction, formally a [2 + 2] cycloreversion, to generate a key intermediate for the degradation. |
