We report the complete GNO solar neutrino results for the measuring periods GNO III, GNO II, and GNO I. The result for GNO III (last 15 solar runs) is [54.3-9.3+9.9(stat)±2.3(syst)]SNU(1σ) or [54.3-9.6+10.2(incl. syst)] SNU (1σ) with errors combined. The GNO experiment is now terminated after altogether 58 solar exposure runs that were performed between 20 May 1998 and 9 April 2003. The combined result for GNO (I + II + III) is [62.9-5.3+5.5(stat)±2.5(syst)] SNU (1σ) or [62.9-5.9+6.0] SNU (1σ) with errors combined in quadrature. Overall, gallium based solar observations at LNGS (first in GALLEX, later in GNO) lasted from 14 May 1991 through 9 April 2003. The joint result from 123 runs in GNO and GALLEX is [69.3±5.5(incl. syst)] SNU (1σ). The distribution of the individual run results is consistent with the hypothesis of a neutrino flux that is constant in time. Implications from the data in particle- and astrophysics are reiterated

A new approach to the Friedländer synthesis of quinolines is described. Polysubstituted quinolines are readily prepared under milder conditions than in other existing methods through a gold(III)-catalysed sequential condensation/annulation reaction of o-amino aromatic carbonyls and ketones containing active methylene groups.

3-Unsubstituted indoles undergo regioselective alkylation at the 3-position of the indole nucleus through gold-catalyzed conjugated addition type reaction with α,β-enones. 3-Substituted indoles undergo C-2 alkylation. Sequential C-3/C-2 gold catalyzed alkylation of the indole with dibenzylidene acetone gives a poly­cyclic indole b-annulated with a seven-membered cycle.
