摘 要: | The first example of fused phosphorus heterocyclic 4- l′-(β-bromoethyl)-4'-oxo-3'-prop yl-1′, 2′, 3′, 4-tetrahydro-1, 3, 2-benzodiazaphosphorin-2′-sulfide]-1, 2, 3, 4, 4a, 4b, 5, 6-octahydro -6-oxo-5-propyl-3, 4b, 4a-thiazphosphaphenanthridine 4a, 2′-dioxide was synthesized in excellent yield by refluxing a mixture of 1-(2-bromoethyt)-2, 3-dihydro-3-propyl-l, 3, 2-benzodiazaphos phorin-4(1H)-one 2-oxide with carbon disulfide in benzene in the presence of triethylamine.
