资源简介：
The
possibility of fluoride-mediated selective dephosphonylation
of α-diazo-β-carbonyl phosphonates such as the Ohira–Bestmann
reagent has been proposed and executed. The resulting α-diazocarbonyl
intermediates undergo a (3 + 2)-cycloaddition at room temperature
with conjugated olefins and benzynes. Interestingly, under the current
conditions, the resulting cycloaddition products underwent either N-acylation (with excess α-diazo-β-carbonyl
phosphonates) or Michael addition (with conjugated olefins).
