THE BETA-NAPHTHOL VS. HYDRO-NAPHTHOL CONTENTION. [PDF]
JAMA: The Journal of the American Medical Association, 1889 "Who shall decide when doctors disagree?" says the poet, with as close accordance with a general truth as reason and poetry require. Yet we shall always find, even in the case of the disagreement of doctors, criteria by which rational decision may be reached. In the first place, the opinions of individual doctors, as well as of persons not doctors, are

Enhancement of Dissymmetry Factors Through Axial Elongation of Hetero[n]helicenes
Angewandte Chemie, EarlyView.A benzofuran scaffolding strategy enables the synthesis of hetero[9]‐, [12]‐, and [15]helicenes. Structural and chiroptical analyses demonstrate that systematic axial elongation increases helical distortion and significantly amplifies luminescence dissymmetry.
