摘要
The synthesis of a new enantiomerically pure diene, (S)-(+)-1 is reported. The absolute configuration of 1 was determined by non-empirical analysis of its CD spectrum. The synthesis and resolution of the racemic beta-diketone 4 into its constituent enantiomers by the SAMP-hydrazone method is described. The enantiopure beta-diketone (S)-(+)-4 was then converted to diene (S)-(+)-1 by a two-stage reaction sequence. Structural analysis of the products by H-1 and C-13 NMR spectroscopy is also presented.
