New analogs of the pyripyropene family of ACAT inhibitors via α-pyrone fragmentation and γ-acylation/cyclization

The pyridine moiety of pyripyropene A was replaced with other aromatic and heteroaromatic substituents via α-pyrone degradation followed by dienolate γ-acylation and in situ cyclization.
