Stereoselective synthesis of a 12-acetoxyazadiradione analogue
摘要:
The synthesis of the 12-acetoxy enone 15 related to the limonoid azadiradione has been achieved in 12 steps (16% overall yield) starting from tricyclic diester 1. The key steps involve intramolecular 1,3-dipolar cycloaddition of a nitrile oxide and a Stille coupling reaction of a vinyl iodide with a stannylfuran. (c) 2005 Elsevier Ltd. All rights reserved.
