Abstract

Although a-diazocarbonyl compounds, which serve as precursors to a-keto carbene/carbenoid or a-diazonium carbonyl intermediates, have been used extensively in synthetic organic chemistry, there has been a recent resurgence of their utilization in intramolecular ring closure Elegant and practical examples of this utilization include the syntheses of gibberellin/gibberellic acid3 and thienamycin.* In this paper we report on the ...
