Addition of organometallics to chiral 3-pyridyl oxazolines gave high diastereoselectivity at the 4-position of the pyridine nucleus. Absoluteconfiguration was determined by x-ray analysis.

The addition of 2-(lithiomethyl)indole 2 to the enantiopure oxazolinylpyridine 18 followed by acidic treatment afforded a mixture of tetracyclic compounds 21a and 21b in a 3:2 ratio. The major epimer 21a was converted to tetracycle 25a, a tetracyclic ABDE substructure of Strychnos alkaloids.
