, p. 1041 - 1043 (2010)
A highly efficient method for the synthesis of fluorinated 2,6-trans dihydropyrans via BF3·Et2O-promoted Prins cyclization of allenic alcohols and aldehydes is developed. Various 2,6-trans fluorodihydropyrans are obtained in moderate
Stereoelectronic versus steric tuning in the prins cyclization reaction: Synthesis of 2fi-trans pyranyl motifs
Hu, Xu-Hong,Liu, Feng,Loh, Teck-Peng
supporting information; experimental part, p. 1741 - 1743 (2009/09/06)
The use of carboalkoxyl allenic alcohol for the efficient synthesis of pyranyl motifs via Prlns cycllzatlon Is described. This method provides easy access to 2,6-trans dlhydropyrans In good yield and high dlastereoselectlvlty.
A CONVENIENT SYNTHESIS OF α-HYDROXYALLENES BY THE REACTION OF PROPARGYL IODIDES WITH ALDEHYDES IN THE PRESENCE OF STANNOUS HALIDE
Mukaiyama, Teruaki,Harada, Taira
, p. 621 - 624 (2007/10/02)
In the presence of stannous halide, propargyl iodides react with aldehydes in an aprotic solvent to yield α-hydroxyallenes as major products, particularly in the cases of γ-substituted propargyl iodides, along with β-hydroxyacetylenes.
