Unexpected Reactivity of Acetylenic ω-Ketoesters toward TBAF and t-BuOK; New Cascade Reactions Affording Allene and Oxetane Derivatives†
journal contribution
posted on 2001-07-20, 00:00 authored by Florence Wendling, Michel MieschThe reactivity of acetylenic ω-ketoesters toward tetra-n-butylammonium fluoride and potassium tert-butoxide was studied. These cascade
reactions proceeded smoothly and afforded either electrophilic allene derivatives or highly functionalized oxetane derivatives in moderate to
high yields.
