The present invention relates to certain β-decalone derivatives which can impart useful odor notes of the pheromone or costus type. The present invention concerns the use of the compounds in the perfumery industry to impart such odor notes as well as to the compositions or articles that contain these compounds.

Catalysts generated from Pd 2 (dba) 3 and biphenyl ligands 4 and 7 efficiently promote the coupling of amides and carbamates with unactivated vinyl triflates and tosylates, to provide enamides in good to excellent yields.

The invention is directed to the use of compounds of formula (I), as fragrant agents. In this formula: - R3 and R4 are independently a hydrogen atom, a C1-C6 alkyl group or a C2-C6 alkenyl group, R5 is a C1-C6 alkyl group, a C2-C6 alkenyl group or a (CH2)0-2-aryl group, R6 is a C1 -C6 alkyl group, a C2-C6 alkenyl group, a (CH2)0-2-aryl group or a C5- C6 cycloalkyl or cycloalkenyl group, and R7 is a hydrogen atom, a C1-C6 alkyl group or a C2-C6 alkenyl group; or R3, R4 and R5 are as above defined, and R6 and R7 together with the carbon atom to which they are attached form a C5-C6 cycloalkyl or cycloalkenyl group.

1,3,4-oxadiazine derivatives, in equilibrium with their corresponding trisubstituted enamine isomers, are obtained in a regiospecific way from cyclohexanone enamines and ethoxycarbonyl aroyl diimides. Such an equilibrium is not present in analogous oxadiazine systems, derived from aryl aroyl diimides.

Vinyltriflates can be converted into the corresponding enamines by treatment with a secondary amine, Cs2CO3 and a catalyst generated from Pd(OAc)2 and rac-BINAP.
