Benzoanellated Centropolyquinanes, 15. Benzoanellated Fenestranes with [5.5.5], [5.5.5.6], and [5.5.5.5] Frameworks: The Route from 1,3-Indandione to Fenestrindan
The synthesis and spectroscopic characterization of several 23 and 29 is the keystep of the synthetic strategy. The new benzoanellated [5.5.5]-, [5.5.5.6]-, and [5.5.5.5]fenestranes, synthetic variant involving the one-pot cyclodehydration/deincluding the parent difuso-centrotriindan 7, the parent tetraketalization of the dispiro-ketal diol 29 is particularly convefuso-centrotetraindan 8 (”fene...
متن کاملDirect organocatalytic asymmetric heterodomino reactions: the Knoevenagel/Diels-Alder/epimerization sequence for the highly diastereoselective synthesis of symmetrical and nonsymmetrical synthons of benzoannelated centropolyquinanes.
Amino acids and amines have been used to catalyze three component hetero-domino Knoevenagel/Diels-Alder/epimerization reactions of readily available various precursor enones (1a-l), aldehydes (2a-p), and 1,3-indandione (3). The reaction provided excellent yields of highly substituted, symmetrical and nonsymmetrical spiro[cyclohexane-1,2'-indan]-1',3',4-triones (5) in a highly diastereoselective...
متن کاملCis 530 Assignemnt 2
One important generalization to emerge from Table 1 is that the accuracy rate improves for each corpus using the tagger trained on both corpora instead of the taggers trained on a single corpus. This exemplifies that common result that accuracy improves by simply including more training data, even if it from a different genre. However, it is interesting to note that the accuracy improved more f...

In the structure of the title compound, C(20)H(34)O(2)Si, a cis,trans,cis,cis-[4.5.5.5]fenestrane derivative, the geometry of the central C(C)(4) substructure shows considerable distortion from an ideal tetra-hedral arrangement towards planarity, with two opposite bridgehead bond angles of 128.87 (18) and 122.83 (17)°. The other bridgehead angle of the trans-bicyclo-[3.3.0]octane subunit is als...
متن کاملrac-cis,cis-Dicarbonyldichlorido{1-[2-(diphenylphosphanyl)benzyl]-3-mesitylimidazol-2-ylidene}ruthenium(II) dichloromethane monosolvate
The Ru(II) atom in the title compound, [RuCl(2)(C(31)H(29)N(2)P)(CO)(2)]·CH(2)Cl(2), exhibits a distorted octahedral coordination environment. The bond angles of the cis substituents at the Ru(II) atom range from 82.72 (9) to 97.20 (3)°. This mol-ecule is of inter-est in the field of catalytic transfer hydrogenation.
