Participants

Reaction Steps

Using the method described by J. Nokami et al., J. Am. Chem. Soc. 2001, 123, 9168-9169, cyclopropanecarbaldehyde was reacted with (1S,2R,5S)-1-[(2S)-but-3-en-2-yl]-5-methyl-2-(propan-2-yl)cyclohexanol [this crotylation reagent was derived from (+)-menthol] to afford the product as an oil. Yield: 600 mg, 4.75 mmol, 100%. 1H NMR (400 MHz, CDCl3), characteristic peaks: δ 5.45-5.63 (m, 2H), 2.86-2.92 (m, 1H), 2.33-2.41 (m, 1H), 2.20-2.29 (m, 1H), 1.69-1.72 (m, 3H), 0.47-0.56 (m, 2H), 0.27-0.37 (m, 1H), 0.16-0.26 (m, 1H).
