METHOD OF PRODUCING DERIVATIVES OF 1-PYRAZOLINA Russian patent published in 2016 - IPC C07D231/54

Abstract RU 2598077 C1

FIELD: chemistry.

SUBSTANCE: invention relates to organic synthesis, particularly to production of tricyclic derivatives of 1-pirazolina, containing 9-13 carbon atoms, an aldehyde group and 5-merous cycle with diaza-group. Method is based on reaction C₂-C₆ Omega-alkenylboronic norbornene, for example 5-vinyl-2-norbornene with nitrous oxide (N₂O) at a temperature of 100-250 °C and total pressure of 2-150 ATM.

EFFECT: it is suggested a single-step method of producing novel tricyclic derivatives of 1-pirazolina appropriate to the formula a, where n = 0÷4.
