摘要
Exposure of the chiral, non-racemic, allylic ester 7 to LDA/TMSCl provides acid 8 and subsequent iodolactonization of 8 provides one lactone (9) with total stereoselectivity. X-ray analysis of the corresponding alpha-methylbenzylamides of 8 and 9 confirmed the absolute stereochemistry of the trans-anti-trans lactone (9). The synthesis is completed by treatment of 9 with the enolate of t-butyl acetate affording tetrahydrofuranyl derivative 12.
