Versuchsvorschrift
3,3-dimethyl-δ-valerolactone was treated with HI in HOAc, followed by diazomethane to give methyl 3,3-dimethyl-5-iodo-pentanoate. This material and the aldehyde from U.S. Pat. No. 4,851,409, Example 24, Step 1 were assembled using Method L. The thiol was from Example 80, Step 4. This compound showed signals at m/e 548 (M+1) and 570 (M+Na) in a fast atom bombardment mass spectrometer (FAB-MS).
