of pestalotiopsones D (4) and E (5) were elucidated through total synthesis of both the R and S enantiomers, allowing for the assignment of the stereochemistry of the natural compounds as the (+)-S enantiomers. The key steps include homologation of a substituted benzoic acid to the appropriate phenylacetate derivative using Birchreductivealkylation, an oxa-Michael cyclization induced by microwave irradiation

compounds for the first time. The key steps included a recently described homologation of benzoic acid to the analogous phenyl acetate using Birchreductivealkylation conditions, acylation of the appropriate phenyl acetate derivative, and a selective reduction and spontaneous biomimetic lactonization to yield the 3-isochromanone skeleton. The synthesized natural products were evaluated for their biological
