Synthesis of benzo-homotriasterenedioneSome of these results have been communicated in a preliminary note [2], where a different numbering system and correspondingly different names have been used.The tri- and tetra-cyclic compounds encountered in this work are derivatives of homologues of well known ring systems, namely of adamantane, twistane, isotwistane and triasterane. They are named on the basis of the trivial names preceded by the prefix ‘homo’ [1a] and are numbered accordingly [1b] as follows: For each formula (a to e) the trivial name used in this paper is given below, together with the systematic name in the polyclo-nomenclature [1c], for which the numbering is self-evident. abicyclo [3.3.2]dec-9-eneb9-oxa-10a-homoadamant-10-ene ≡ 7-oxa-tricyclo[4.3.1.14,8]undec-2-enec5-oxa-10a-homotwist-10-ene ≡ 8-oxa-tricyclo[5.4.0.04,9]undec-2-ened5-oxa-9a-homo-isotwist-9-ene ≡ 2-oxa-tricyclo[4.4.1.03,9]undec-7-enee9a-homotriaster-9-ene ≡ tetracyclo[3.3.2.02,8.04,6]dec-9-ene (1974)
Bicyclo[4. 1. 0]hept-3-ene-2, 5-dione (homo-p-quinoneThe prefix ‘homo-’ before a trivial name signifies that the system (chain or ring) has been enlarged by one carbon member. The special case of double bond to cyclopropane ‘enlargement’ has received individual attention in connection with Winstein's homoconjugation concept. For this reason and for the sake of brevity we shall, in the following text, refer to compounds 1 a and 2 a as syn- and anti-bis-homo-p-quinone and to compound 4 as homo-p-quinone.) and its bamford stevens reaction (1974)
The double bamford-stevens Reaction with Tricyclo [5.1.0.03,5] octane-2,6-dione (Bis-homo-p-quinoneThe prefix «homo-» before a trivial name signifies in general that the system (chain or ring) has been enlarged by one carbon member. The special case of double bond to cyclopropane modification has received individual attention in connection with Winstein's homoconjugation concept. For brevity's sake we call in the following text compounds (1) and (2) anti- and syn-bis-homo-p-quinone.). Synthesis and Reactions of 4,5-Dihydro-4,5-methano-1,7-diaza-7aH-indene (4,5-Homo-1,7a-diaza-indene)For brevity's sake we call compounds in this series homo-diaza-indenes. Other names of 5, in accord with the IUPAC-rules of nomenclature would be 7,8-dihydro-7,8-methano-pyrazolo [2,3a] pyridine or 1,10-diaza-tricyclo[5.3.0.04,6]deca-2,7,9-triene. (1974)
Synthesis of 3,7-Diacetoxy-benzo-bullvaleneThe systematic name is: 3,7-diacetoxy-9,10-benzo-tricyclo[3.3.2.02,8]deca-3,6,9-triene, which is used in the Experimental Part. (1976)
Formation of 5-Hydroxy-indan-2-one from Attempts to Hydrolyse 9-Ethylenedioxy-bicyclo[3.3.1]nonane-3,7-dione (1977)
