Process for the production of compounds useful in perfumery

摘要

Process for producing compounds useful in perfumery including isochromans and acylated indane hydrocarbons with an alkylene oxide or with a lower acyl halide in the presence of a hydrocarbon or hydrocarbon mixture containing C5 and C10 alkanes at a temperature of from -20 DEG C. up to -5 DEG C. In the case of forming isochromans, the resulting alcohol is reacted, in situ, with a lower alkanol and a formaldehyde precursor at temperatures of from 20 DEG C. up to 80 DEG C.
