标 题:Synthesis of navelbine analogs
发明人：MAGNUS PHILIP D; THURSTON LEE S
权利人:UNIV TEXAS
摘要:The invention is a de novo synthesis of the norcatharanthine moiety of navelbine. The synthesis includes condensing a Grignard reagent prepared from an amine-protected R(+)-piperidinyl methanol with an N-protected 2-methoxyoxalyl indole. The indole N-protecting group is removed to provide a 2-methoxyindole hydroxy ester which is coupled to vindoline. After removal of the amineprotecting group from the piperidinyl group, ring closure to the indole moiety provides dihydrodesethyl navelbine. Other derivatives and analogs of navelbine with potential clinical applications in cancer chemotherapy may be readily synthesized. The synthesis opens a route to a wide variety of navelbine modifications, including modifications at or near the tryptamine bridge.

摘要:Process for the synthesis of alpha -chlorinated chloroformates, and new alpha -chlorinated chloroformates. The invention relates to a new process for the manufacture of alpha -chlorinated chloroformates and, to new alpha -chlorinated chloroformates as new industrial products. The process according to the invention consists of a synthesis, by catalytic phosgenation, of alpha -chlorinated chloroformates of the formula: in which: R represents a substituted or unsubstituted hydrocarbon radical and m represents an integer superior or equal to one, this synthesis consisting in reacting phosgene with the aldehyde R-CHO)m, in the presence of a catalyst which is an organic or inorganic substance which is capable in a medium containing an aldehyde of the formula R-CHO)m, phosgene and, possibly, a solvent, of generating a pair of ions one of which is an halogenide anion and the other is a cation which is sufficiently separated from said halogenide anion so as to give to the latter a nucleophilic power enabling it to react with the function(s) aldehyde of the molecule R-CHO)m.

摘要:The first de novo synthetic pathway to the exceptionally rare C5-nor stemmadenine natural product, conolidine, and the first asymmetric synthesis of any member of this natural product class arc described. C5-nor stemmadenine compositions are also described. These compounds, for example,(+/- )-,(+)- and (-)-conolidine are potent and efficacious non-opioid analgesics in tonic and persistent pain.
