Chemical predisposition in synthesis: application to the preparation of the pyrrolidine natural products, plakoridines A and B
摘要:
The pyrrolidine natural products, plakoridines A and B, as well as an array of unnatural analogues, have been prepared using a five-step synthetic sequence modelled on a biogenetic theory. The key transformation involves a `Mannich/Michael/intemal-redox' cascade, which proceeds in yields of 31-63%. (c) 2006 Elsevier Ltd. All fights reserved.

An array of novel analogues of the marine oxylipins, the manzamenones and plakoridines, have been prepared in divergent fashion using an approach modelled on a biogenetic theory. Many of the target compounds show potent inhibition of DNA polymerases alpha and beta and human terminal deoxynucleotidyl transferase (TdT).
