A concise approach to the core structures of pinnaic acid and halichlorine
Yang, Sung-Hyun,Clark,Caprio, Vittorio
, p. 2981 - 2990 (2011/02/28)
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
