Book excerpt: Robert Burns Woodward was the star of 20th-century organic chemistry. An MIT graduate by age 19, Woodward's ingenious notions about organic synthesis and his artful methodology were astounding. He is most famed for his synthesis of vitamin B12,which he undertook with Albert Eschenmoser, and for the orbital symmetry rules he developed with Roald Hoffmann. This volume presents Woodward's most celebrated papers and lectures--including the famous Cope lecture. Insightful commentaries and rarely seen photographs are also included.
