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

New Synthetic Route to Spiroacetals. The 3,4-Dihydro-2H-pyran Approach to (+/-)-Talaromycin B
The nucleophylic cleavage of the oxirane (9) by the organocuprate derived from 3-ethyl-6-lithio-3,4-dihydro-2H-pyran (7) was the key step in a synthesis of racemic talaromycin B (12).A similar synthesis of desethyltalaromycin B (15) from (9) and 6-lithio-

A Synthesis of Talaromycin B
The nucleophilic cleavage of the oxirane (4) by the organocuprate derived from 6-lithio-3-ethyl-3,4-dihydro-2H-pyran (3) was the key step in a synthesis of racemic talaromycin B (7).
