This paper describes a simple two-step sequence involving the catalytic inversion of the steroidaltype A/B ring juncture to an antipodal A/B ring juncture. This procedure has been employed in the synthesis of (-)-podocarpic acid (enontiopodocarpic acid) from (+)-dehydroabietic acid. Skeletons having

## Abstract The irradiation of 1โ(dehydroabietoyl) imidazole **(3)** gave no Type II elimination product but yielded instead compounds **6** and **7** by migration of the imidazolylcarbonyl group from C(4โฒ) to C(6โฒ) of the abietan moiety, probably via a cyclobutanol intermediate. Similarly, irradia
This is the first of five books in the *Amino Acids, Peptides and Proteins in Organic Synthesis* series. Closing a gap in the literature, this is the only series to cover this important topic in organic and biochemistry. Drawing upon the combined expertise of the international "who's who" in amino
