variation sufficient to produce enormous effects on reactivity in intramolecular nucleophilic catalysis, the efficiency of intramolecular general base catalysis changes by a factor of less than ten. Catalytic efficiency is also low in absolute terms, reaching a limiting effective concentration of ca. 100M, to be compared with 108M for intramolecular nucleophilic catalysis uncomplicated by strain. The difference

An efficient two‐step synthesis of structurally and functionally diverse thiophenol‐ and (cyclo)alkyl‐derived malonicacid half thioesters (MAHTs) and phenol‐derived malonicacid half oxyesters (MAHOs) has been achieved using cheap, readily available and easily handled starting materials. The synthesis of the MAHTs and MAHOs (the majority of which have not been previously reported) is readily scalable
