Usage

General Description

1-(octahydro-7,7,8,8-tetramethyl-2,3b-methano-3bH-cyclopenta[1,3]cyclopropa[1,2]benzen-4-yl)ethanone, also known as OTTME, is a synthetic chemical compound with a complex molecular structure. It is a ketone derivative that is commonly used as a fragrance ingredient due to its pleasant and long-lasting odor. OTTME is also used in the production of perfumes, soaps, and other personal care products. Additionally, it is used as a flavoring agent in food products and as a solvent in various industrial applications. However, due to its synthetic nature and potential health hazards, OTTME must be handled and used with caution, following proper safety guidelines and regulations.

Kondakof Acylation of Logifolene/Camphene: A Comparative Study Using Boron Trifluoride Etherate/Stannic Chloride as Catalysts

The Kondakof acylation of the ectocyclic methylene moiety in comphene (1) and its isoprene homologue longifolene (2) has been studied in acetic anhydride using BF3*OEt2/SnCl4 as catalysts.Ac2O-BF3*OEt2 fails to acylate (1) but gives isobornylacetate (3) (46percent) as the sole product.Acylation of (1) with Ac2O-SnCl4 affords ω-acetyl comphene (4) in a negligible yield (2percent) along with (3) in a much reduced yield (19percent).In sharp contrast, longifolene (2) generates ω-acetyllongifolene (5) with both the catalysts: BF3*OEt2 (24percent) and SnCl4 (16percent).The other compounds isolated in the former case are isolongifolene (6) (50percent) and transannular acetate (7) (2percent); in the latter case, (6) (17percent), (7) (5percent) and the novel tetracyclic methylketone (8) (11percent) are the co-products.The precurser for (8) has been shown to be the isomerized hydrocarbon (6), on direct acylation with SnCl4 generates (8).
