Ring closure of diethyl 2-methoxy-2-[N-(5-amino-1-benzylimidazolyl-4-carbonyl)amino]malonate: Product structures and pathways of product formation
Abstract Ring closure of the title compound (1) with sodium methoxide in methanol yielded three products, one 5∶6-fused and two 5∶7-fused heterocyclic systems: 9-benzyl-2-methoxycarbonylhypoxanthine (2), 3-benzyl-4,5,7,8-tetrahydro-6-methoxy-6-methoxycarbonyl-6H-imidazo[4,5-e][1,4]-diazepine-5,8-dio...

| abstract |
Abstract Ring closure of the title compound (1) with sodium methoxide in methanol yielded three products, one 5∶6-fused and two 5∶7-fused heterocyclic systems: 9-benzyl-2-methoxycarbonylhypoxanthine (2), 3-benzyl-4,5,7,8-tetrahydro-6-methoxy-6-methoxycarbonyl-6H-imidazo[4,5-e][1,4]-diazepine-5,8-dione (3), and 3-benzyl-4,5,7,8-tetrahydro-6-methoxy-6H-imidazo[4,5-e][1,4]-diazepine-5,8-dione (4). Structures and pathways of formation of all three products have been described. Structures of2 and3 were confirmed by single-crystal X-ray diffraction analyses. |

Structures and pathways of formation of all three products have been described. Structures of2 and3 were confirmed by single-crystal X-ray diffraction analyses.</subfield></datafield><datafield tag="533" ind1=" " ind2=" "><subfield code="f">Springer Online Journal Archives 1860-2002</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Bhan, Anila</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Hosmane, Ramachandra S.</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Zhang, Hongming</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Hosmane, Narayan S.</subfield><subfield code="4">oth</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">in</subfield><subfield code="t">Structural chemistry</subfield><subfield code="d">1990</subfield><subfield code="g">5(1994) vom: Juni, Seite 375-381</subfield><subfield code="w">(DE-627)NLEJ188989943</subfield><subfield code="w">(DE-600)2018832-8</subfield><subfield code="x">1572-9001</subfield><subfield code="7">nnns</subfield></datafield><datafield tag="773" ind1="1" ind2="8"><subfield code="g">volume:5</subfield><subfield code="g">year:1994</subfield><subfield code="g">month:06</subfield><subfield code="g">pages:375-381</subfield><subfield code="g">extent:7</subfield></datafield><datafield tag="856" ind1="4" ind2="0"><subfield code="u">http://dx.doi.org/10.1007/BF02252896</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_USEFLAG_U</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">ZDB-1-SOJ</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_NL_ARTICLE</subfield></datafield><datafield tag="951" ind1=" " ind2=" "><subfield code="a">AR</subfield></datafield><datafield tag="952" ind1=" " ind2=" "><subfield code="d">5</subfield><subfield code="j">1994</subfield><subfield code="c">6</subfield><subfield code="h">375-381</subfield><subfield code="g">7</subfield></datafield></record></collection>
