Cyclopropanation of aliphatic alkenes. The reactions were conducted on 1 mL scale under the listed conditions using 20 mM alkene and 3 equiv of EDA (added over 3 h by syringe pump as a 30% (v:v) solution in DMF). The yields were determined by GC using dodecane as internal standard. The stereochemistry of products was assigned based on NMR analysis (see the Supporting Information); the absolute stereochemistry of 10 was not assigned.
