The structure of the title compound, C16H22O4, was determined by X-rays atT=290 K.M r =264.320, triclinic, space groupP¯1,a=8.4857(9),b=10.0613(5),c=10.1499(7) A,α=122.019(5)°,β=107.049(8)°,γ=74.892(9)°,V c =696.5 A3,Z=2,D x =1.260 Mg m−3. MoKα radiation (graphite crystal monochromator,λ=0.70926 A),μ(MoKα)=7.03 cm−1. Final conventionalR-factor=0.058,R w =0.088 for 2223 unique reflections and 247 variables. The structure was solved usingMultan andDirdif. The alkylation step in the synthetic prepa...

Abstract The total synthesis of (±)-colorata-4(13),8-dienolide ( 1 ), a sesquiterpene with a rearranged drimane skieleton, is described using 6β, 8aβ-dimethyl-5-methylene-3,4,4aα, 5,6,7,8,8a-octahydro-1(2H)-naphtalenone ( 10 ) as a key intermediate. A new annelation method for butenolides via hydrolysis of a thiohenyl furan is reported.
