  A process for synthesizing a C-7 protected baccatin III compound represented by formula (A), which comprises reacting a 10-deacetylbaccatin III compound represented by formula (B) with a protecting agent and an acylating agent in the presence of a secondary amine and a nitrogen-containing compound. Also, a process for synthesizing a C-7 protected 10-deacetylbaccatin III compound represented by formula (C), which comprises reacting a 10-deacetylbaccatin III compound represented by formula (B) with a protecting agent in the presence of a secondary amine and a nitrogen-containing compound. In both processes the nitrogen-containing compound is selected from a nitrogen-containing heterocycle or a trialkylamine. When the nitrogen-containing heterocycle is selected, it may be an unsubstituted or a substituted pyridine or an unsubstituted or a substituted pyrazine. When a trialkylamine is selected, it may be, for example, triethylamine or diisopropylethylamine. wherein PG 1 represents the organic residue of the protecting agent, PG 2 represents the organic residue of the acylating agent, and R represents a simple or substituted aryl group or a heterocyclic group.

  An efficient, general method for the synthesis of 1,2-hydroxy esters by regioselective nucleophilic opening of 1,2-cyclic carbonate systems has been developed. A reliable and practical route giving access to the taxoid carbonate 2 from the readily available 10-deacetylbaccatin III (13) has been established. Nucleophilic opening of the carbonate 2 with a variety of nucleophiles provided a number of novel C-2 Taxols. Water-soluble taxoid onium salts (e.g., 31e, 31n, 32, and 34b) were also synthesized and studied. A selected number of taxoids were subjected to cytotoxicity and tubulin polymerization assays as well as in vivo studies. The results of these studies are reported herein.
