An enantioselective route to trans-2,6-disubstituted piperidines
摘要:
The synthesis of (S)-2-methyl tetrahydropyridine-N-oxide (4), a key intermediate for the enantioselective construction of trans-2,6-disubstituted piperidines via [3+2] nitrone cycloaddition reaction, is described. Nitrone 4 was elaborated to the fire ant venom alkaloid (+)-solenopsin-A (2) via intermediate 14. (C) 1997 Elsevier Science Ltd.

A convenient route to trans-2,6-dialkylpiperidines by cycloaddition of alkenes to 2-alkyl-2,3,4,5-tetrahydropyridineoxides followed by reductive cleavage of the resulting isoxazolidine is illustrated by a synthesis of the fire ant-venom alkaloid, solenopsin.
