relative configurations could be achieved. In the third route the thioneester 18 was deprotonated with tBuOK. At temperatures below -78 °C, the enolate maintained the cis configuration of the substituents at the tetrahydrofuran ring. The alkylated product 12 could be isolated with a satisfactory cis/trans ratio of 85:15. The modelcompound 12 could be successfully transformed into more hydrophobic derivatives
