✦ Synopsis
e-Sulfenyl radical can be generated from a-chlorosulfide or dithioacetal. The olefin substituent effect on the intramolecular radical cyclization of this type was studied.

## Abstract Petroselinic acid was cyclized via methyl 2‐iodopetroselinate (1) with tributyltin hydride to give methyl __trans__‐ and __cis__‐2‐dodecyl‐1‐cyclopentanecarboxylate (2). The atom‐transfer method with hexabutylditin resulted in the formation of bicyclic γ‐lactones 4 and methyl __trans__‐
