Abstract
Phosphorane ylides and phosphonate anions react smoothly with resin-bound aldehydes and ketones to provide alkenes in good yields and purities (assessed after cleavage of acid-labile PAL anchor to support). The reactions of aldehydes give excellent stereoselectivities. Effective conditions have been developed for carrying out these transformations.
Keywords: Solid-phase synthesis; Combinatorial chemistry; Wittig reaction.
