Model studies to develop a tetracyclization approach mimicking the proposed biosynthesis of the secodaphnane-type alkaloid longeracemine are described. These studies have culminated in the successful implementation of a 3H-pyrrole [4+2] cycloaddition that delivers a longeracemine-like azabicycle containing three contiguous quaternary stereocenters.

text] An efficient and highly stereoselectivesynthesis of functionalized trisubstituted E-olefins from cyclopropyl carbinol derivatives via a Julia-type olefination mediated by an intriguing Lewis acidic system consisting of CeCl(3).7H(2)O and NaI in refluxing acetonitrile is reported. This facile olefination allows for the iterative incorporation of methylcyclopropyl ketone as a C(5) prenylation synthon
