We disclose herein a new approach for the highlydiastereoselective total synthesis of the anti-tumoral agent (±)-Spisulosine. The synthesis was accomplished in seven steps with an overall yield of 10%. The key step involves the transformation of a Morita–Baylis–Hillman into an acyloin, which was subsequently used as substrate in a highlydiastereoselective reductive amination reaction.
