The phosphorylation of N-benzoyl-2-(1,3,3-trimethyl-2-methyleneindoline)acetamide (2) and ω-(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-phosphindol-3-one systems, respectively. The properties of the obtained compounds were studied. Further cyclization of 1,2-
N-苯甲酰基-2-(1,3,3-trimethyl-2-methyleneindoline)乙酰胺 (2) 和 ω-(3-二甲氨基)benzoyl-1,3,3-trimethyl-2-methyleneindoline (6) 的磷酸化与磷 (III) 卤化物反应导致分别形成 2,3-dihydro-4H-1,5,2-oxazaphosphinin-4-one 和 1,2-dihydro-3H-phosphindol-3-one 系统。研究了所得化合物的性质。1,2-二氢-3H-膦醇-3-酮进一步环化为二氢膦并[3,2-c]吡唑。© 2003 Wiley Periodicals, Inc. 杂原子化学 14:23–28, 2003; 在线发表于 Wiley InterScience (www.interscience.wiley.com)。DOI 10.1002/hc.10060
