M. Reggelin et al., TOWARDS POLYKETIDE LIBRARIES - II - SYNTHESIS OF CHIRAL ARACEMIC DIKETIDES AND TRIKETIDES ON A SOLID SUPPORT, Tetrahedron letters, 39(27), 1998, pp. 4801-4804
A new fluoride ion cleavable linker serves as starter unit for iterati
ve asymmetric aldol reactions on a solid support. The synthetic protoc
ol relies on the baron enolate chemistry of D. A. Evens and a cyclic r
eestablishment of key functionalities. It entails the opportunity for
the generation of di-and triketide libraries. (C) 1998 Elsevier Scienc
