The conformation of 3-acetyl-Δ3-carene and 3-carene-7-al

The conformations of 3-acetyl-Δ3-carene and 3-carene-7-al were established on the basis of the spectral data and molar Kerr constants. © 1971 Consultants Bureau

Stereochemistry of reduction of 4-acetyl-3α,4α-epoxycarane by sodium borohydride

It was shown that the hydrogenolysis of 4-acetyl-3α,4α-epoxycarane using NaBH4 is accomplished stereoselectively in harmony with its steric structure. © 1979 Plenum Publishing Corporation

Preparation and structure of 2-acetyl-2,3-epoxycarane

1. 2-Acetyl-α-2,3-epoxycarane which exists in solution as a single gauche conformer with minimal polarity was synthesized by the epoxidation of 2-acetyl-2-carene by perphthalic acid. 2. The conjugation in the system of double bonds in 2-acetyl-2-carene is disturbed due to acoplanarity of the C=C-C=O fragment. © 1982 Plenum Publishing Corporation

Conformations of cyclic bromoarsenites and the electrical parameters of arsenic bonds

1. It has been shown that 2-bromo-l,3,2-dioxaarsenanes exist in chair conformation with axially oriented As-Br bonds. 2. Polarity and polarizability parameters have been found for the As-O and As-Br bonds in 2-bromo-l,3,2-dioxaarsenanes. 3. The so-called α-effect is stronger in the O2AsBr group than in the O2AsCl group. © 1977 Plenum Publishing Corporation
