摘要:
Optically active organic compounds are prepared starting from optically inactive reactants by means of an optically active agent which influences the course of the reaction. In particular optically active compounds having a "meso" type carbon atom undergo an intramolecular ring closure in the presence of an optically active agent to yield an optically active product having one additional ring. The present process is particularly useful in the preparation of optically active bicyclic diketones which are important intermediates in the total synthesis of steroids.

WHEREIN Z is a moiety selected from the group consisting of:
AND WHEREIN R1, R2, R3, R4, R5, R6, R7, R8, R9 and R10 are the same or different and each is selected from the group consisting of methyl and hydrogen and wherein R11 is selected from the group consisting of methyl, ethyl and hydrogen; and wherein X is selected from the group consisting of bromo, chloro, hydroxyl, benzyloxyl and alkoxyl and a process for preparing such compounds involving intimately admixing a methyl substituted cyclohexadienone having the structure:
WITH ONE OF THE FOLLOWING ACETYLENIC COMPOUNDS HAVING THE STRUCTURES:
The compounds thus produced are valuable intermediates used in producing chemical compounds having valuable organoleptic properties; particularly in perfumery, in flavoring foodstuffs and in flavoring tobacco.
WHEREIN R1, R2, R3, R4, X1, X2, X3, X4 and X5 are certain substituents selected from hydrogen, halogen, alkyl, alkenyl, halogenated alkyl, halogenated alkenyl, alkoxy, hydrocarbyl, halogen-substituted hydrocarbyl, carboxy, hydroxy-substituted alkyl, alkoxy-substituted alkyl, and hydroxy-substituted alkoxyalkyl, with at least two of X1, X2, X3 and X4 being halogen, and X6 is halogen. The bicyclic ketones are made by treating a corresponding tricyclic hemiketal with phosphorus halide and hydrolyzing. The bicyclic ketones are useful as chemical intermediates and as insecticides.
