実験手順

Methylcyclobutanone (3.200 g, 38.043 mmol) was dissolved in 200 ml THF and allylmagnesium bromide (190.21 ml, 190.21 mmol) was added in one portion. The mixture was stirred for 4 h at RT, hydrolyzed with water and extracted. The combined organic extracts were dried over MgSO4 and evaporated and purified via glass col. Chrom. (25-75% hex. in EtOAc). 1-Allyl-3-methylcyclobutanol (2.250 g, 46.9% yield) was obtained as a mixture of cis-trans isomers approx 4:1 (where the major compound is the one Me-cis to OH) based on NMR.
