A novel one-pot synthesis of cyclopropanols based on the reaction of magnesium carbenoids with lithium enolate of ketones

The reaction of magnesium carbenoids with lithium enolate of ketones resulted in the formation of cyclopropanols in moderate to good yields. These reactive species (i.e., magnesium carbenoids and lithium enolate of ketones) were generated from 1-chloroalkyl p-tolyl sulfoxides with i-PrMgCl and ketones with LDA in the reaction medium at −78 °C in a one-pot reaction.
