The present invention relates to the field of perfumery and concerns some bi-cyclo derivative of formula (I), wherein R1 represents a hydrogen atom or a C1-2 alkyl group; R2 represents a hydrogen atom or a methyl group; and A represents a group of formula C3-5 alkanediyl group; at least one of said R1 or R2 represents a group containing at least one carbon atom; and said compound being in the form of a E or Z isomer or of a mixture thereof. Said compounds are valuable perfuming ingredients capable of imparting lily of the valley and citrus notes.
A heterogeneous fluoride catalyst was found to enable the straightforward formation of alkenyl nitriles from the reaction of aldehydes and simple or substituted acetonitriles, in the presence of commercially available silazanes and in solvent-free conditions. The protocol afforded the products in good to excellent yields with selectivity values dependent on the nature of the substrates. It represents
