Usage

General Description

1,5,5-trimethylcyclohexene is a chemical compound with the molecular formula C9H16. It is a colorless liquid with a mild, sweet odor, and it is insoluble in water but soluble in organic solvents. 1,5,5-trimethylcyclohexene is commonly used as an intermediate in the production of various chemicals, including fragrances, pesticides, and pharmaceuticals. It is also used as a solvent and as a flavoring agent in the food industry. 1,5,5-trimethylcyclohexene is considered to be relatively stable and non-reactive under normal conditions, but it can be hazardous if ingested, inhaled, or absorbed through the skin, and it may pose environmental risks if released into the atmosphere or waterways.

Facile synthesis of isodamascone and its analogs

Synthesis of isodamascone and its analogs, the commercially important aroma compounds, have been accomplished from the readily available 1,5,5-trimethyl-2-cyclohexen-1-ol via a short, facile, and simple sequence of reactions in excellent yield. Copyright Taylor & Francis Group, LLC.

The transformation of 36 bis(homoallylic) alcohols VII to alkenones IX and X via β-cleavage of their potassium alkoxides VIIa in HMPA has been investigated (cf.Scheme 2).These studies have established an order of β-cleavage for 2-propenyl, 1-methyl-2-propenyl, 2-methyl-2-propenyl, 1,1-dimethyl-2-propenyl, and benzyl groups in alkoxides 49a-56a and have allowed a comparison between the β-cleavage reaction and the oxy-Cope rearrangement in alkoxides 74a-83a.As illustrative synthetic applications, a two-step preparation of propenyl ketones 15-42 from carboxylic esters is described, together with syntheses of ar-turmerone (48), α-damascone ((E)-71), β-damascone ((E)-109), and β-damascenone ((E)-111).
