✦ Synopsis


The radical cyclizations of bromo ketals derived from the Birch-alkylation products of a-tetralones are described. The carbon carbon bond formation proceeds in a regio-and stereoselective way. The intra-and intermolecular trapping behavior was also explored.

## Abstract A new synthesis of bromo‐ and iodomethyl‐substituted tetrahydrofurans has been devised. The sequence starts with the conversion of aryl‐functionalized bis(homoallylic) alcohols **1** into __N__‐alkenoxythiazole‐2(3__H__)‐thiones **6** or pyridine‐2(1__H__)‐thiones **7**. When photolyzed
