: The intramolecularPauson-Khandreaction of 1,8-enynes derived from salicylaldehyde derivatives has been investigated. Substrates derived from salicylaldehyde itself reacted poorly in this reaction, but related substrates containing ortho-tert-butyl substituents participated quite effectively and in many cases the cyclizations proceeded with high levels of diastereoselectivity.
