Syed, Erfan Asif (1993) PHYTOCHEMICAL INVESTIGATIONS OF THE CHEMICAL CONSTITUENTS OF BUXUS SPECIES AND SYNTHESES WITH METAL COMPLEXES. PhD thesis, University of Karachi, Karachi.
This thesis presents phytochemical research on two medicinal plants. Studies on the leaves of Buxus sempervirens and roots of B. papillosa have led to the isolation and characterization of six new steroidal bases. In addition, eight more compounds have also been reported for the first time fromboth these plants. Some spectral generalizations made for Buxus alkaloids based on a comparative literature is included. The thesis further presents some work on syntheses with metal complexes. The reaction of bisnaphthyl acetylene with cyclopentadienylbis carbonyl cobalt has resulted in the formation of three new products. Besides, some reactions were done with rhodium complex to develop four new six-membered ring systems. A few Pd-Cu catalyzed reactions of terminal acetylenes with different aryl halides are also presented in this thesis.
