A concise approach to the core structures of pinnaic acid and halichlorine

An efficient and flexible synthetic approach to the core structures of pinnaic acid and halichlorine is described using spirocyclic nitrone 4 as a key intermediate. 1,3-Dipolar cycloaddition of 4 with dipolarophile 8 provides access to the azaspirocyclic

DIASTEREOSELECTIVITY IN THE CYCLIZATION OF 1-(2-(BENZYLOXYMETHYL)-3-BUTENYL)-5-ETHOXY-2-PYRROLIDINONES

1-(2-(Benzyloxymethyl)-3-butenyl)-5-ethoxy-2-pyrrolidinones 12 cyclize upon formic acid treatment to indolizinones.The effect of some substituents α to the iminium carbon atom on the diastereoselectivity of the cyclization is discussed.
