Precursor 13 was prepared by the highly flexible sequence via siloxycyclopropanecarboxylates as published earlier; the alkylating agent in this case was 1-bromomethylnaphthalene: (a) Reichelt, I.; Reissig, H.-U.

Compounds 16-20 were obtained by LDA-promoted alkylation of N-cyclohexyl imines of the corresponding cycloalkanones with 1-(2-iodoethyl)naphthalene as an electrophile. For analogous procedures, see: (a) Fleming, I.; Godhill, J. J. Chem. Soc., Perkin Trans. 1 1980, 1493-1498. (b) Fleming, I.; Godhill, J. J. Chem. Soc., Perkin Trans. 1 1982, 1563-1570.

29, 31, 33, and 39 were synthesized starting from cyclopentanone or cyclohexanone as described in ref 12. Diastereomers 36 and 42 were prepared similarly with the corresponding ketal as a starting material.

Chair-like folding in the transition structure of 33 or 36 with the methoxycarbonyl group in an equatorial position would lead to compounds as depicted in Scheme 6; on the other hand, no comparable chair folding seems to operate for the reactions presented in Scheme 5.
