  摘要：

  A series of trans-tetrahydro-4-hydroxy-6-[2-(2,3,4,5-substituted-1H-pyrrol-1-yl)ethyl]-2H-pyran-2-ones and their dihydroxy acids were prepared and tested for their ability to inhibit the enzyme HMG-CoA reductase in vitro. Inhibitory potency was found to increase substantially when substituents were introduced into positions three and four of the pyrrole ring. A systematic exploration of structure-activity relationships at these two positions led to the identification of a compound ((+)-33, (+)-(4R)-trans-2-(4-fluorophenyl)-5-(1-methylethyl)-N,3-diphenyl-1-[(tetrahydro-4-hydroxy-6-oxo-2H-pyran-2-yl)ethyl]-1H-pyrrole-4-carboxamide) with five times the inhibitory potency of the fungal metabolite compactin.

  Highly efficient synthesis of chiral tetrasubstituted 2,3-dihydrofuran derivatives has been realized by Cu-catalyzed asymmetric [4 + 1] cycloadditions of alpha-benzylidene-beta-ketoester with a diazo compound. Following this methodology, a series of optically active multifunctionalized dihydrofurans were prepared in high yield with up to 96% ee and 99/1 dr.
