Diastereoselective synthesis of 2-arylmethylene-6-hydroxyspiro[4.5]deca-7-ones via FeCl3·6H2O-catalyzed spiroannulation/hydride transfer of 6-(5-arylpent-4-yn-1-yl)-7-oxabicyclo[4.1.0]heptan-2-ols

In the presence of a catalytic amount of FeCl3·6H2O, 6-(5-arylpent-4-yn-1-yl)-7-oxabicyclo[4.1.0]heptan-2-ols underwent attack of the pendant acetylene at the iron-activated oxirane to give a vinylic carbocation. Hydride transfer from the carbinol carbon to the newly formed cation center furnished 2-arylmethylene-6-hydroxyspiro[4.5]deca-7-ones in excellent stereoselectivity and good yields.
Facile synthesis of azaspirocycles via iron trichloride-promoted cyclization/chlorination of cyclic 8-Aryl-5-aza-5-tosyl-2-en-7-yn-1-ols

A simple and efficient FeCl3-promoted cyclization/chlorination of cyclic tosylamine-tethered 8-aryl-2-en-7-yn-1-ols was observed. The reaction proceeded instantaneously at 23 °C in air to afford (Z)-4- (arylchloromethylene)-substituted azaspiro
