Condensation-ring Expansion Reaction of Formyl[2.2.1]bicyclic Carbinols with Para-substituted Phenyl Amines: Application to the Preparation of [3.2.1]bicyclic N-aryl-1,2,3-oxathiazolidine-2-oxide Agents
No full text[[abstract]]Individual reaction of camphene-derived endo-formyl[2.2.1]bicyclic carbinol and that of camphor-derived exo-formyl[2.2.1]bicyclic carbinol with parent and para-substituted phenyl amines gave regio- and stereospecific corresponding [3.2.1]bicyclic (para-substituted) phenyl amino ketones. Mechanism of each reaction was discussed. Some camphor-derived [3.2.1]bicyclic amino ketones were reduced to [3.2.1]bicyclic (para-substituted) phenyl amino alcohols, which were then treated with mesyl chloride to provide [3.2.1]bicyclic N-phenyl/aryl-1,2,3-oxathiazolidine-2-oxide agents. The mechanism of this final reaction was discussed as well.[[note]]SC
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
