摘要
The phosphorylation of N-benzoyl-2-(1,3,3-trimethyl-2-methyleneindoline)acetamide (2) and omega-(3-dimethylamino)benzoyl-1,3,3-trimethyl-2-methyleneindoline (6) with phosphorus(III) halides resulted in the formation of 2,3-dihydro-4H-1,5,2-oxazaphosphinin-4-one and 1,2-dihydro-3H-phos-phindol-3-one systems, respectively. The properties of the obtained compounds were studied. Further cyclization of 1,2-dihydro-3H-phosphindol-3-one into dihydrophosphindolo[3,2-c]pyrazole was carried out.
