Summary of scientific research
A. Reaction mechanism and reaction stereochemistry: Early experimental and theoretical studies relevant to terpene biosynthesis on the course and stereochemistry of acid-catalyzed cyclizations of terpenoid polyenes (biogenetic isoprene rule, together with L. Ruzicka, 1953); the stereochemical interpretation of the biogenetic isoprene rule, together with D. Arigoni and L. Ruzicka (1955); the experimental demonstration of strain release control of the oxidation of alcohols with chromic acid (1955) and of stereoelectronic control of SN2- reactions (1970); experimental and theoretical studies on nitrogen inversion (1969). B. Chemical synthesis: development of new reactions and reagents: Introduction of heterocyclic fragmentation reactions into organic synthesis (1952); epoxy-ketone -> alkinone-fragmentation (1967); amide acetal version of Claisen rearrangement (1969); methods for making C, C-bonds: enamino-iminoester condensations (1964), sulfide-contractions (1968), dimethyl-methylidene-iminium iodide (1971) and α-Chloro-nitrone reactions (1972). C. Chemical synthesis: synthesis of complex natural products and related structures: Synthesis of the alcaloid of the autumn crocus, Colchicin (1959); synthetic routes to corrins (1964, 1969); synthesis of vitamin B12 (collaboratively with R.B. Woodward) (1972); synthetic studies related to the problem of vitamin B12biosynthesis (1980). D. Contemporary studies: Chemical etiology of nucleic acid structure; experimental and theoretical studies relevant to the problem of designing chemical models of biogenesis.
