Reaction of adamantane series olefins with N-bromosuccinimide
摘要:
Features of allyl bromination of sterically hindered adamantane series olefins with N-bromosuccinimide were investigated. A series of unsaturated mono- and polybromo adamantane derivatives was synthesized. The configuration of compounds obtained was established using 2D NOESY NMR spectroscopy.

AbstractFunctionally substitutedoxiranes were synthesized by epoxidation of unsaturated compounds of the adamantane series with m-chloroperoxybenzoic acid. Adamantyl-substituted epibromohydrins reacted with nitrogen, oxygen, and sulfur nucleophiles to give only halogen substitution products. 2-(Adamantan-1-yl)-3-hydroxypropanoic acid was obtained by the reaction of 2-(adamantan-1-yl)-2-(bromomethyl)oxirane with 98%

The possibility of sterically hindered allyl thiocyanates undergoing sigmatropic rearrangement was demonstrated. On the basis of kinetic studies and quantum chemical calculations, the intramolecular isomerization mechanism of 1-[(E)-3-thiocyanoprop-1-en-1-yl]adamantane to 1-(1-isothiocyanoprop-2-en-1-yl)adamantane was confirmed.
