Abstract: A chemical compound having the formula: wherein R is an alkyl group and M.sup.+ counterion is an alkali metal, and a process of making the same.

Abstract: The invention provides compositions that include conjugates of a fatty acid molecule, preferably cis-docosahexaenoic acid, and antipsychotic agents. The conjugates are usefull in treating psychotic conditions such as schizophrenia.

Abstract: An efficient protocol for the synthesis of taxol, taxol analogs and their intermediates is described. The process incudes the attachment of the taxol A-ring side chain to baccatin III and for the synthesis of taxol and taxol analogs with variable A-ring side chain structures. A rapid and highly efficient esterification of O-protected isoserine and 3-phenylisoserine acids having N-benzyoloxycarbonyl groups to the C-13 hydroxyl of 7-O-protected baccatin III is followed by a deprotection-acylation sequence to make taxol, celphalomanninne and various analogs, including photoaffinity labeling candidates.

Abstract: A method for producing paclitaxel is accomplished by first esterifying C-7-CBZ baccatin III with a C3'-N-CBZ-C2'-O-protected (2R, 3S)-3-phenylisoserine side chain to form a first intermediate. Next, the carbobenzyloxy groups at C-7 and at the C3' nitrogen site of the first intermediate are respectively replaced with hydrogen and PhCO to produce a second intermediate that is next deprotected at C2' by replacing the protecting group with hydrogen. The C2' protecting group is a benzyl-type protecting group, preferably benzyloxymethyl or benzyl. Excess amounts, such as six equivalents, of the side chain are preferably employed. DMAP and a dialkylcarbodiimide are also preferably used during esterification. Various preferred reaction temperatures, times, and purification steps are disclosed.

Abstract: A method of producing docetaxel comprises the esterification of C7, C10 di-CBZ 10-deacetyl baccatin III and an N-CBZ C2'-protected 3-phenyl isoserine side chain wherein C2' is protected by a hydrogenatable benyl-type protecting group. The C7, C10 carbobenzyloxy groups are then replaced with hydrogen and the carbobenzyloxy group at the C3' nitrogen site is replaced with t-butoxycarbonyl. Finally, the resulting compound is deprotected at C2' by replacing the benzyl-type protecting group with hydrogen to produce docetaxel. The esterification preferably employs an excess, such as six equivalents, of the side chain for each equivalent of the C7, C10 di-CBZ 10-deacetyl baccatin III. Benzyloxymethyl is the preferred protecting group at C2'.

Abstract: The synthesis of paclitaxel obtained from the semi-synthesis of taxol using a protected baccatin III backbone which is esterified with a suitably protected side chain acid, thereby producing an intermediate which may be acylated and deprotected to produce paclitaxel.
