Abstract
AbstractA mild and facile synthetic method via convergent assembly of two reactive intermediates generated in situ has been developed. This method provides an efficient way to construct six- and seven-membered N-heterocycles containing a biaryl linkage. This reaction features a gem-difunctionalization process of diazo compounds with cyclic hemiaminals, delivering α-hydroxyl-β-amino ester derivatives with a tertiary carbon center through a formal C–O bond-insertion transformation.
