An Improved Synthesis of 14α‐Hydroxy‐15,16‐dehydro‐17‐ oxomarcfortine A; A Key Intermediate in the Synthesis of 14α‐ Hydroxymarcfortine A.

Abstract An improved synthesis of 14α-hydroxymarcfortine A from marcfortine A was achieved by means of a redesigned synthesis of the key intermediate [4α-hydroxy-15,16-dehydro-17-oxomarcfortine A ( 8 ).
