The study explores the isomerization of D-glucose to D-mannose using a resin catalyst in carbon dioxide-free water under nitrogen, yielding D-mannose phenylhydrazone. It also investigates the synthesis of amines derived from 3-phenyl-1-indanone through the Mannich reaction with various amines (dimethylamine, diethylamine, piperidine, and morpholine) and formaldehyde, resulting in low yields and unstable products. Further reductions and hydrogenations of these products led to the formation of indene derivatives and aminoalcohols, but no significant pharmacologic activity was observed. Additionally, the study examines the Mannich reaction of p-nitroacetophenone with different amines and formaldehyde, yielding p-(di)-alkylamino-p-nitropropiophenones, which were further reduced to aminoketones and reacted with phenylhydrazine to form pyrazolines.
