Insertion reactions of electron-deficient alkenes with chromium aminocarbenes derived from podocarpicacid generally give aryl ketone products derived from ring opening of an aminocyclopropane and subsequent enamine hydrolysis, the exception being alkenyl sulphones which give products derived from insertion of the carbene into the β-CH bond of the alkene.

Cyclomanganation reactions of podocarpicacidderivatives containing aldehyde, ketone, ester, or oxime groups as directing functionalities have been investigated. Attempted complexation of amide-containing ligands proved generally to be unsuccessful whereas benzylic ketones gave their corresponding tetracarbonyl complexes in high yields. Complexation of ligands containing either two potential sites
