Facile synthesis of enol ethers by cleavage of α-bromoacetals and α-bromoketals mediated by SmI2
摘要:
alpha -Bromocyclicacetals, alpha -bromocyclicketals and alpha -bromocyclicthioketals, derived from cyclic and acyclic ketones and aldehydes, reacted with samarium diiodide at -78 degreesC in THF to furnish the corresponding enol ethers or thioenol ethers containing hydroxy or thiol moieties in high yields.
