The effect of substituents on the reactivity and stereoselectivity of the SmI 2 /Pd(0)-promoted ring-contraction of 5-alkynylpyranosides has been examined using substrates substituted only at selected positions. While formation of 2-ethynylcyclopentanols takes place efficiently, an internal alkyne d
## Abstract (__Z__)‐2‐Aryl‐1‐(2‐cyanoethyl)ethenylphosphonates were synthesized by the hexamethylphosphoramide‐promoted sequential transformation of tetra‐alkyl methanediphosphonates, by the action of potassium tert‐butoxide, and then by acrylonitrile and aldehydes. © 2002 Wiley Periodicals, Inc. H
