(+)-(3aS,6R,7aR)-perhydro-6-methyl-3-methylene-2-benzo[b]furanone - coumarinic, lactonic, tonka, daffodil, very powerful.; perhydro-6-methyl-3-methylene-2-benzo[b]furanone possesses a very powerful odor of the coumarinic, fat, lactonic type, with a balsamic bottom note reminiscent of the odor of daffodil. This is an odor note which is very close to that of coumarin and which is best represented in (+)-(3aS,6R,7aR)-perhydro-6-methyl-3-methylene-2-benzo[b ]furanone, a preferred compound of the invention Ref: Gaudin, Jean-Marc, Use of furanones as perfuming ingredients, United States Patent 5,464,824, November 7, 1995; Jean-Marc Gaudin, Synthesis and Organoleptic Properties of p-Menthane Lactones, Tetrahedron, Volume 56, Issue 27 , 30 June 2000, Pages 4769-4776	(-)-(3aR,6S,7aS)-perhydro-6-methyl-3-methylene-2-benzo[b]furanone - Not available Ref: Gaudin, Jean-Marc, Use of furanones as perfuming ingredients, United States Patent 5,464,824, November 7, 1995; Jean-Marc Gaudin, Synthesis and Organoleptic Properties of p-Menthane Lactones, Tetrahedron, Volume 56, Issue 27 , 30 June 2000, Pages 4769-4776

(+)-(6R)-3(RS)-3,6-dimethyl-4,5,6,7-tetrahydro-1-benzofuran-2(3H)-one - it develops a phenolic/coumarin-like odour, making it a useful alternative to coumarin. It also has a completely original, minty odoriferous note much appreciated by perfumers Ref: Frerot, Eric; & Bagnoud, Alain; Method for preparing a gamma-unsaturated beta-lactone and use thereof as an aromatic and flavouring ingredient, United States Patent Application 20020098271, July 25, 2002	(-)-(6S)-3(RS)-3,6-dimethyl-4,5,6,7-tetrahydro-1-benzofuran-2(3H)-one - not available
