Abstract

Abstract Thioalkylated Meldrum's acid is easily by treatment of Meldrum's acid with an aldehyde and thiophenol in the presence of catalytical amounts of piperidinium acetate ([RIGHTWARDS ARROW] 1–6, Table 1). The adducts 1–6 are crystalline, stable compounds and they can be caused to react directly with nucleophiles and dienes (see 3 [RIGHTWARDS ARROW] 7–12, Scheme 1). The regeneration of the parent olefin is ...
