    • The TMS-protected alkyne corresponding to 27 was also prepared, but the derived nitrile was volatile and difficult to obtain in reasonable yield. However, sufficient material with the TMS-protected alkyne was carried forward to confirm the stereochemistry of the conjugate addition reactions, see Ref. 24.
