New methods are described for the preparation of 5,6‐dihydro‐11‐morphanthridone, 5‐substituted 5,6‐dihydro‐11‐morphanthridones and nuclear halogenated derivatives. Basic Grignard reagents convert these ketones to carbinols, which through dehydration affords a convenient route to straight chain and cyclic 11‐aminoalkylidene derivatives.
