FIELD: chemistry.
SUBSTANCE: invention relates to novel biologically active compounds - substituted benzoxazin isoindoles of formula 1: 8,9-dimethoxy-5,5-diphenyl-6a, 11-dihydro-5H-benzo[4,5][1,3]oxazin[2,3-a]isoindol-11-on of formula 1.1; 8,9-dimethoxy-5,5-diethyl-6a, 11-dihydro-5H-benzo[4,5][1,3]oxazin[2,3-a]isoindol-11-on of formula 1.2, protecting sunflower shoots against adverse impact of herbicide of 2,4-dichlorophenoxyacetic acid and method of obtaining them. Method of obtaining 8,9-dimethoxy-5,5-diphenyl-6a, 11-dihydro-5H-benzo[4,5][1,3]oxazin[2,3-a]isoindol-11-on of formula 1.1; 8,9-dimethoxy-5,5-diethyl 6a, 11-dihydro-5H-benzo[4,5][1,3]oxazin[2,3-a]isoindol-11-on of formula 1.2 includes interaction of o-aminophenyldiethyl-(diphenyl)carbinoles wth substituted 2-formyl-4,5-dimethoxybenzoic acids with ratio 1:1. Difference of claimed method from method-analogue lies in single-stage process. 
EFFECT: creation of efficient method of substituted benzoxazin isoindoles.
