Notes:
Lithiation of 5,6-dihydro-2H-pyran (7) gives a mixture of dihydropyranyllithiums 14 and 2. 14 rearranges to 2, and 2 in turn undergoes a [1,4] sigmatropic shift to give the lithium cyclopropyl-enolate 3. Lithiation of nerol oxide 6 gives the lithio derivative 24, which likewise undergoes [1,4] shifts to give cyclopropyl-enolates 28 and 29.
