摘要
The synthesis of the AB spiroketal fragment of spongistatin 1 (altohyrtin A) has been accomplished utilizing the addition of a metalated pyrone to an aldehyde followed by acid catalyzed spirocyclization. A stereoselective copper (I) promoted conjugate addition of vinylmagnesium bromide was used to establish the C11 stereogenic center. (C) 1998 Elsevier Science Ltd. All rights reserved.
