The tetrahydrofuranyl radical, generated from THF with Et3B in the presence of air, was found to react with aldehydes threo-selectively to afford alpha-substituted tetrahydrofuran-2-methanols, the common structural motifs of biologically active acetogenin polyketides, in moderate yields.

Two complementary methods for the construction of the ring system of CP-263,114 (1), one relying on the Grob fragmentation reaction and the other on a sequential photolytic alkoxy radical fragmentation-reduction, are described. (C) 1999 Elsevier Science Ltd. All rights reserved.

A new synthetic route for construction of the core moiety of zaragozic acids from 2,5-furandimethanol (2) is described. This synthesis involves highly stereocontrolled transformation of 2 into 7-oxabicyclo[2.2.1] heptane derivative 13, and the Grob fragmentation-reduction-iodo acetalization reaction (one-pot process) of 13 as a key step to give 16.
