英文摘要	Mass spectrometric behaviour of 2,2a,3.4-tetrahydro-4-methyl-2a-phenyl-2-(thiophen-2-yl)-1H-azeto [2,1-d][l 5]benzothiazepin-1-one-5-oxide and 2.3-dihydro-2, 4-diphenyl-1, 5-benzothiazepine-1-oxide/-1, I dioxide have been studied with the aid of mass-analyzed ion kinetic energy spectrometry and accurate mass measurements under electron impact ionization. The monooxide derivatives showed a tendency to eliminate an alkene or an oxygen atom. 1H-Azeto[2 1-d1[1,5 ]benzothiazepin- 1 -one- 5-oxide could also eliminate the thiophen-2-ylketene molecule via a reverse [2+2] cycloaddition. 2,3-Dihydro-2,4-diphenyl-1,5-benzothiazepine1-oxide/-lo 1-dioxide could eliminate SO2 or SO, respectively. The structure of 2. 2a. 3 4-tetrahydro-4-methyl-2a-phenyl-2-(thiophen-2-yl)-1H-azeto[2,1-d]EI,5]benzothiazepin-1-one-5-oxide was identified on the basis of its fragmentation. The identification was supported by the fragmentations of model compound, 2.3-dihydro-2.4-diphenyl-1 5-benzothiazepine- I -oxide /- 1, 1 -dioxide.; http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000229624800005&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701 ; Chemistry, Multidisciplinary; SCI(E); EI; 中国科技核心期刊(ISTIC); 中国科学引文数据库(CSCD); 9; ARTICLE; 3; 274-279; 21
