- In addition to 77 % of 12, 4 % of a dimeric product and 2 % of monocyclic products were obtained
- The stereochemistry of 12 was assigned by 1H NMR analysis. the H1-H2 coupling constant of the major (exo), isomer was observed to be 3. 7 Hz. In case of 16, the coupling constant of the major isomer (exo), was 3. 8 Hz while that of the minor isomer (endo), was 6. 9 Hz. In cyclopropane derivatives, cis, coupling constant is generally larger than the corresponding trans, coupling constant
