Easier said than done, for I had an idea of how the reaction worked in theory, but I had no clue what most of the reagents in my protocol were actually doing. What should I take out? What to add? I was completely lost. Ever since, I made it a habit to look up all the ...

Tables of ^1H and ^(13)C NMR chemical shifts have been compiled for common organic compounds often used as reagents or found as products or contaminants in deuterated organic solvents. Building upon the work of Gottlieb, Kotlyar, and Nudelman in the Journal of Organic Chemistry, signals for ...
All other commercially available reagents were used as received. Tri-tert-butyl ester 9 A solution of DiBAlH in hexanes (0.55 ml, 1 m, 0.55 mmol) was added to lactone 5 (74 mg, 0.19 mmol) in dry THF (2 ml) at −78 °C and the resulting solution was allowed...
The minor diaseteroisomer 19, with the incorrect stereo- chemistry at the stereocenter marked (Scheme 3) probably results from [3,3]-sigmatropic rearrangement of the corresponding E-silylk- etene acetal, which is formed as the minor geometric isomer during the enolisation/silylation reaction....
摘要: The intramolecular titanium-mediated cyclopropanation reaction of an oxa-ester bearing a terminal double bond followed by appropriate oxidation and dehydrohalogenation allows easy access to an aryl-fused oxacyclooctenone, an effective precursor of (±)-heliannuols A, K and L....
