The anti-tumor compound maytansine was originally isolated from the Ethiopian shrub Maytenus serrata. Development of a multistep synthesis of maytansine involved compound 1 as a key precursor. (Tet. Lett. 1975, 31, 2643-2646.) Propose an efficient synthesis of 1 starting with acetylene, acetone, and formaldehyde as the only sources of carbon atoms. Select the appropriate reagents for each step.
