    摘要: Compounds represented by the structural formulae ##STR1## wherein n is an integer 0 or 1; A, B and C each independently represent hydrogen or alkyl having from 1 to 3 carbon atoms, provided that when n is 0 at least one of A, B or C cannot be hydrogen; R represents hydrogen or an alkyl having from 1 to 6 carbon atoms; D and E each independently represent hydrogen or alkyl having from 1 to 6 carbon atoms, provided that the sum of the carbon atoms in D and E does not exceed 6, provided that, in the bicyclo compounds, at least one of A, B, C, D or E must be an alkyl; m is an integer 1 through 8; F and G represent hydrogen or alkyl having from 1 to 3 carbon atoms; X represents ##STR2## WHEREIN P IS AN INTEGER 0 THROUGH 2 AND I and J each independently represent hydrogen or methyl, provided that if p is 0 then m must be greater than 2; provided that the sum of the carbon and oxygen atoms in the compound is no greater than 23, are useful as fragrances or as components in fragrance compositions. These compounds have very pleasant, strong and long-lasting aromas. Novel compounds are also disclosed.

    摘要: A chiral phosphorus-based ligand, in single enantiomer form, which is capable of complexing a transition metal atom and of acting as a ligand in asymmetric chemical catalysts, which comprises the partial structureR.sup.1 R.sup.2 P--O--C--X--Y--C--O--PR.sup.1 R.sup.2 (I)wherein each of X and Y is C or a heteroatom; the C--X--Y--C chain forms part of a linearly-fused bicyclic structure; and either R.sup.1 and R.sup.2 are each independently H or an organic group of up to 20 carbon atoms, including alkyl, fluoroalkyl, aryl, alkylaryl, alkoxy, aryloxy, and alkylaryloxy, or PR.sup.1 R.sup.2 is cyclic such that R.sup.1 and R.sup.2 are covalently linked, optionally with additional substituents.
