SmI2-mediated 3-exo-trig cyclizations of β,γ-unsaturatedcarbonylcompounds to generate cyclopropanols are not generally observed processes. The reported examples are limited to β,γ-unsaturatedcarbonylcompounds that possess ester groups conjugated with the alkene unit. The results of the current study show that this cyclization also occurs when other substitution patterns are present on the alkene
