Abstract

FERRARINI, Renan S.; PRINCIVAL, Jefferson L.; COMASSETO, João V.  and  DOS SANTOS, Alcindo A.. A concise enantioselective synthesis of (+)-endo-brevicomin accomplished by a tellurium/metal exchange reaction. J. Braz. Chem. Soc. [online]. 2008, vol.19, n.5, pp.811-812. ISSN 0103-5053.  http://dx.doi.org/10.1590/S0103-50532008000500002.

A homoenolate generated by tellurium/lithium exchange reaction was employed in a straightforward enantioselective synthesis of (+)-endo-brevicomin in 70% yield and 84.4% e.e.

Keywords : tellurium/lithium exchange; homoenolate; epoxide opening.
