ABSTRACT:
An Iodine catalyzed (3, 5)-thionium-ene-type cyclization for the facile construction of various multisustituted tetrahydrothiopyrans was successfully developed from aldehyde (aromatic and aliphatic) and 6-methylhept-5-en-2thiol, 6-methyl-2-phenyl hept-5-en-2-thiol and 2, 6-dimethylhept-5-en-2-thiol in the presence of iodine under mild and neutral conditions. This method is simple, convenient and cost-effective.
