stannadithiane compounds containing different endocyclic functional groups -including ether (1), diether (2), lactone (3), and spirolactone (4)- were prepared. The conformational landscape has been fully determined for the 8-membered representative (compound1) resulting in a distorted crown form with the butyl chains adopting an extended conformation. The infrared and Raman spectra of stannadithiane

We synthesized novel macrocyclic dithiolactones bearing endocyclic ether, polyether and lactone groups using new stannadithianes as tin templates in the condensation reaction with acid dichlorides and demonstrated an extension of this method toward synthesizing spirotetrathiolactones of controlled size. The structures of all synthesized compounds were characterized by spectroscopic methods.
