摘要

A general procedure for direct lithiation of deoxyvasicine was developed. 3-Lithiodeoxyvasicine intermediate was found to react with various aliphatic ketones providing derivatives of 3-(hydroxyalkyl)deoxyvasicine in good yields. Similar reaction with 4-alkylcyclohexanones yielded respective trans-adducts exclusively. This novel protocol was successfully scaled-up to result in multigram quantities of vasicine-containing core building blocks suitable for production of compound libraries. The described synthetic methodology offers access to a wide range of compounds with potentially beneficial biological profiles.
