## Abstract Trisubstituted 1,4,5,6,‐tetrahydro‐7__H__‐indolones are obtained in a one‐pot synthesis from conjugated nitroolefins and α‐ketoenamines derived from α‐amino esters and cyclohexane‐1,2‐dione. In some cases bicyclo[3.2.1]octan‐8‐one and 1,2‐oxazine __N__‐oxide derivatives are isolated.
Three insect pheromones, (2!,5S)-P-methyl-5-hexanolide, (3z,llSl-3,11-dimethyl-2-nonacosanone, and serricornin, were synthesized in optically pure forms by using newly developed asymmetric reactions as key steps. Optically active insect pheromones have been one of the challenging targets of organic
