title: Selective addition of organolithium reagents to BF2-chelates of beta-ketoesters.
abstract: A short, mild, and highly chemoselective addition of organolithium reagents to a BF(2) complex of 3-oxopropanoates has been developed. The methodology allows straightforward preparation of various 1,3-dioxa-BF(2) complexes and subsequently leads to the formation of 1,3-diketones starting from the corresponding 3-oxopropanoates.
