S9A-06 SESSION 9A

Electrochemical Synthesis, Structure Elucidation and Antibacterial Evaluation of 9a-aza-9a-chloro-9a- homoerythromycin A

Electrochemical synthesis, structure elucidation and antibacterial evaluation of 9a-aza-9a-chloro-9ahomoerythromycin A were carried out. It was found that the anodic oxidation of 9a-aza-9a-homoerythromycin A via electrogenerated reactive chlorine species leads to the chlorination of lactam nitrogen in high yield provided the pH of the reaction mixture is maintained above 3. NOESY spectra reveal...

9-phenyl-3,4,4a,9a-tetrahydrotriptycene and 9-phenyl-1,2,3,4,4a,9a-hexahydrotriptycene

rac-7,7′,9,9′-Tetra­phenyl-9a,9a′-bi(7,8,9,9a-tetra­hydro-6aH-penta­leno[1,2,3-ij]naphthalen-8-one)

The racemic title compound, C(54)H(38)O(2), consists of two C-linked penta-leno[1,2,3-ij]naphthalenone moieties, the crowded aryl ring substitution on the cyclo-pentane rings forcing the two segments to assume a conformation which has pseudo-twofold rotational symmetry, with a dihedral angle between the naphthalene substituent groups of 55.30 (8)°. In each segment, the two phenyl rings have dif...

Introduction to the INLG'06 Special Session on Sharing Data and Comparative Evaluation

The idea for this special session had its origins in discussions with many different members of the NLG community at the 2005 Workshop on Using Corpora for Natural Language Generation (UCNLG’05, held in conjunction with the Corpus Linguistics 2005 conference at the University of Birmingham in July 2005), and subsequently at the 10th European Natural Language Generation Workshop (ENLG’05, held a...
