Two complementary strategies for the synthesis of febrifugine are detailed based on previously developed chemoenzymatic approaches to the 3-hydroxypiperidine skeleton. The introduction of the quinazolone-containing side chain in both strategies was based on an N-acyliminium ion-mediated coupling reaction.

The synthetic versatility of three chemoenzymatically prepared hydroxypiperidine building blocks has been explored, resulting in a library of enantiopure functionalized piperidines. Key steps involved N-acyliminium ion-mediated CC-bond formation and cross-metathesis reactions, after which full deprotection led to the set of free 3-hydroxypiperidines. (C) 2010 Elsevier Ltd.
