FIELD: chemistry.
SUBSTANCE: invention relates to a method for synthesis of 3,4-epoxycarane of formula I
with simultaneous production of 3-caren-5-one of formula II
and 3-carene-2,5-dione of formula III
, involving the following: 3-carene is treated with diluted hydrogen peroxide in acetonitrile in conditions for catalytic action of manganese sulphate in the presence of sodium bicarbonate and salicylic acid with subsequent extraction of the reaction mixture with methylene chloride, vacuum distillation of crude epoxy and release of 3,4-epoxycarane with 88% purity and 45% output. 3-caren-5-one II and 3-carene-2,5-dione III are separated through chromatograph on an inverted C-18 phase with output of 13% and 7% respectively.
EFFECT: design of a method for synthesis of intermediate compounds for a range of medical, industrial and perfume preparations.
