FIELD: chemistry.
SUBSTANCE: present invention relates to a process for the preparation of adamantylated furans, which are intermediates for fine organic synthesis. Method consists in adamantylation of furans with 1-adamantanol in a nitromethane medium in the presence of a Lewis acid, as which aluminum triflate or bismuth was used in an amount of 10 mole%, at a temperature of 25–80 °C for 2–4 hours according to the scheme:
.
EFFECT: simplification of the process by reducing the amount of catalyst used to ensure a higher yield of the desired products, as well as the possibility of varying substituents in the furan ring.
