General Description

1,2,3,4,4aα,5,6,8aα-Octahydronaphthalene, also known as cis-decalin, is a bicyclic hydrocarbon with the chemical formula C10H18. It is a colorless, flammable liquid with a faint, sweet odor. This chemical is commonly used as a solvent in various industrial and laboratory applications, as well as a component in the production of perfumes, insecticides, and pharmaceutical drugs. It is also found naturally in certain essential oils and plant extracts. Due to its low toxicity and odor, 1,2,3,4,4aα,5,6,8aα-Octahydronaphthalene is widely used in the production of personal care and cosmetic products. It is important to handle this chemical with care, as prolonged exposure or inhalation can cause irritation to the respiratory system and skin.

INTRAMOLECULAR DIELS-ALDER REACTIONS OF DIENAMINES WITH ACRYLATES: TRENDS IN STEREOSELECTIVITY UPON SUBTITUTION

Intramolecular Diels-Alder reactions of all-trans ethyl 10-diethylamino-2,7,9-decatrienoate and 11-diethylamino-2,8,10-trienoate occur readily to produce trans and cis-fused products in ratios of 85:15 and 55:45, respectively.

Experimental determination of the activation parameters and stereoselectivities of the intramolecular Diels-Alder reactions of 1,3,8-nonatriene, 1,3,9-decatriene, and 1,3,10-undecatriene and transition state modeling with the Monte Carlo-Jumping between Wells/molecular dynamics method

Experimental activation parameters for the intramolecular Diels-Alder reactions of 1,3,8-nonatriene, 1,3,9-decatriene, and 1,3,10-undecatriene have been measured, and the Monte Carlo-Jumping between Wells/Stochastic Dynamics [MC(JBW)/SD] method, which gives relative free energies of activation, was tested as a means to predict stereoselectivities. The predictions are compared to experimental results, and to predictions from quantum and molecular mechanics methods.
