Podocarpic acid (1) and totarol (2) have been converted into five diterpenoids reported to have been isolated from the Neem tree.The synthetic diterpenoids have been compared with the naturally occurring diterpenoids but only the structure of nimbidiol (23) has been confirmed.The structure for margosolone, which was reported as (19), has been revised to (20) after synthesis of both (19) and (20).
Palladium-catalyzed carbonylative cyclization via trapping of acylpalladium derivatives with internal enolates. Its scope and factors affecting the C-to-O ratio

The Pd-catalyzed carbonylative cyclization reaction involving ω-acyl-substituted acylpalladium derivatives can proceed via intramolecular trapping with either C- or O-enolates; the preferential formation of either 5- or 6-membered rings dictates the C-to-
