, p. 1624 - 1634 (2007/10/03)
A nickel-promoted intramolecular cyclization of 1,3-diene with the tethered carbonyl group was developed using the catalyst generated by reduction of Ni(acac)2 with DIBAL-H in the presence of PPh3. It was found that the addition of 1

A totally stereoselective total synthesis of epi-lupinine (1) has been developed that starts with methyl sorbate (6).Alkylation of 6 with bromide 8 gave diene 10, which was elaborated into the imino Diels-Alder precursor 17.Thermolysis of 17 provided excl
A STEREOSELECTIVE TOTAL SYNTHESIS OF EPI-LUPININE
Bremmer, Martin L.,Weinreb, Steven M.
, p. 261 - 264 (2007/10/02)
An intramolecular imino Diels-Alder reaction has been used both to construct the quinolizidine ring system and to set the proper relative stereochemistry of the alkaloid epi-lupinine (1).
