The totalsynthesis of the title compound has been accomplished. Among the key steps were (i) a conjugate additionRobinson annulation-type sequence (see 4), (ii) intramolecular carbomercuration (see 3), (iii) a reduction−ketonization sequence (see 25), (iv) cycloetherification of an unactivated methylene group (see 28), and reductive amination (see 1). A highly preliminary SAR profile suggests that
