Intrigued by hitherto known procedures such as in acidic media regarding the Boc-elimination, where an inseparable mixture was obtained due to the presence of the acid-labile acetonide group, we investigated an alternative method and were surprised to find that NaH could effect prominently to eliminate the Boc function smoothly after desilylation of 8a, finally leading to the desired Cbz-containing substrate 9. It is of great importance to note that the Boc-elimination with NaH in this case requires the presence of the neighboring hydroxyl group. The reason for such an unusual elimination reaction has not been yet clarified.
