ABSTRACT
The selective mono-allylation of 1,3-diketone containing compounds is described. The reaction proceeds under mild reaction conditions and in moderate to high yield (66-99 %). Using this procedure to access the key mono-allylated intermediate, the hitherto difficult to access 3-allyl chromones were synthesized in excellent yield (87-98 %). Finally, the utility of this newly developed procedure was showcased through the rapid synthesis of the scaffold of the xyloketal family of natural products.
