Abstract
On heating tosylates of ethyl 2-alkyl-2-methyl-3-hydroxy-3-phenylpropanoate (R=Me, 1b; R=Et, 6) in o-dichlorobenzene at 170 °C, ethyl 1-methyl-2-phenyl- and 1,2-dimethyl-3-phenylcyclopropanecarboxylates, 3, and 8, were formed in both 5% yield, respectively, whereas the alkyl migration products, ethyl 3-alkyl-2-methyl-3-phenylpropenoates, were not produced. The mode of the reaction of the methyl group with the cationic carbon was described.
