Abstract: A compound of formula wherein either the dotted line indicates the location of a double bond, n is equal to 1 and R represents a hydrogen atom or a methyl radical, or the dotted line indicates the location of a single bond, n is equal to 0 and R represents a hydrogen atom, is useful as a perfuming ingredient for the preparation of perfuming compositions and perfumed products, to which it imparts odor notes of the lily of the valley type.

Abstract: The compounds of the formula wherein the symbols R1, R2, R3 and R4 represent, independently of one another, a hydrogen atom or a linear or branched, saturated or unsaturated C1 to C3 lower alkyl radical, are advantageous as perfuming ingredients for the preparation of perfuming compositions and perfumed articles, to which they impart odoriferous notes of the lily of the valley type.

Abstract: Compounds consisting of indan derivatives of the formula: ##STR1## Wherein X or Y represents an aldehyde or an acetal group and the other represents a hydrogen, and R represents a hydrogen or a methyl group and the t-butyl group is at the 5 or 6 position of the phenyl ring. Where these compounds are useful as perfuming ingredients for the preparation of perfuming compositions and perfumed articles to which they impart floral odor notes.

Abstract: The compounds of formulaa. ##STR1## wherein symbol X represents a --CHO group or a group of formula ##STR2## in which symbols R', taken separately, represent each a C.sub.1 to C.sub.4, linear or branched, saturated or unsaturated alkyl radical, or taken together represent a substituted or unsubstituted C.sub.2 to C.sub.4 alkylene radical; symbol R.sup.2 represents a hydrogen atom or a methyl radical; and R.sup.1 and R.sup.3 are different and represent each a hydrogen atom or a methyl radical;or of formulab. ##STR3## wherein the tert-butyl radical is located in position 5 or 6 of the aromatic ring and, either Y represents hydrogen and X and R.sup.2 have the meaning indicated above, or X and R.sup.2 represent each a hydrogen atom and Y represents a --CH.sub.2 CHO group or a group of formula ##STR4## in which R' is defined as in a.; or of formulac. ##STR5## wherein X and R.sup.

Abstract: The compounds of formula ##STR1## wherein symbol X represents a --CHO group or an acetal group of formula ##STR2## symbols R', taken separately, represent each a C.sub.1 to C.sub.4, linear or branched, saturated or unsaturated, hydrocarbon radical or, taken together, represent a C.sub.1 to C.sub.4 alkylene radical, which may be substituted, and symbol R represents a hydrogen atom or a methyl radical, are useful as perfuming ingredients for the preparation of perfuming compositions and perfumed articles, to which they impart floral type notes.

Abstract: Process for the preparation of alkyl 3-oxo-2-pentyl-1-cyclopentene acetates starting from an epoxy-ester of formula ##STR1## wherein R designates a lower linear or branched alkyl radical of C.sub.1 -C.sub.6 and wherein the wavy line stands for a C--C bond of cis or trans configuration via an isomerization process.

Abstract: A series of compounds showing high antileukemic activity against P388 murine leukemia and increased aqueous solubility due to substitution of --OH for the known --NH.sub.2 at the 3' position of the hexopyranose sugar, i.e., daunosamine.These compounds are coupled products of aglycon selected from daunomycinone, desmethoxy daunomycinone, adriamycinone and carminomycinone. These compounds are coupled at the 0-7 position of the aglycon with an .alpha.
