Total synthesis of (+)-compactin by a double Michael protocol
The total synthesis of (+)-compactin 1 has been achieved by employing a double Michael reaction of (R)-1-acetyl-3-(tert-butyldimethylsiloxy)cyclohexene 16 with methyl crotonate as the key reaction.
A Novel Synthesis Including Asymmetric Synthesis of α,β-Unsaturated γ-Hydroxy Carbonyl Compounds from Enones with Carbon Homologation
Reaction of the carbanion derived from 1-chloroalkyl aryl sulfoxides with enones gave 1,2-adducts in good yields.Treatment of the adduct with potassium benzenethiolate afforded α-phenylthio β,γ-unsaturated carbonyl compound through an α,β-epoxy sulfoxide.
