Synthesis in the Field of Natural Products of Biological Relevance
摘要:
AbstractThe chemical manipulation of the aminosugar, daunosamine, has resulted in the development of new interesting doxorubicin analogues, namely 4′‐epi‐ and 4′‐deoxydoxorubicin, whereas the total synthesis of new aglycones has provided new structural types of the anthracyclines. In the field of beta‐lactams, efforts aimed to the discovery of original anti‐infective compounds have led to the synthesis of novel “penem” derivatives starting from methyl penicillinate.

Some naphthoquinone and anthraquinone ketals have been prepared by anodic oxidation. Regioselective hydrolysis of the above diketals into monoketals is also described. Diels-Alder reaction of (E)-1-methoxybuta-1,3-diene with the monoketal of 1,4-dihydro-4,4-dimethoxy-5-benzyloxynaphthalene proceeded in a regioselective manner.
