NOVEL LACTONE COMPOUND AND NOVEL ETHER COMPOUND

A lactone compound is represented by general formula (A), and an ether compound is represented by general formula (B). In formula (A), R is a hydrogen atom or R1. When R is a hydrogen atom, R′ is R1, the carbon bond (1) is a single bond or a double bond, and the carbon bond (2) is a single bond. When R is R1, R′ is a hydrogen atom or R1, both the carbon bonds (1) and (2) are a single bond, or one of them is a double bond and the other is a single bond. In formula (B), R″ is R1. R1 represents a specific alkyl group, a specific alkenyl group, a specific alkynyl group, or an aryl group. In formulas (A) and (B), n is 0 or 1.

PROCESS FOR PRODUCING WINE LACTONE

The present invention relates to a method comprising (A) reacting a β-keto ester with a 2-halo ester under basic conditions to obtain a 2-aceto-3-methyl-succinic acid ester; (B) reacting the resulting 2-aceto-3-methyl-succinic acid ester with methyl vinyl

131. Determination of the configuration of wine lactone

The intense sweet and coconut-like smelling odorant 1, named 'wine lactone', was isolated from different wine varieties. The chemical structure of this compound, which has not yet been detected in wine or a food, was identified by high-resolution mass spe
