[reaction: see text] L-proline failed to act as an organocatalyst in the homoaldol reaction of ethyl pyruvate; however, it reacted with the ester to give an azomethine ylide that in turn underwent 1,3-dipolar cycloaddition with a second molecule of pyruvate. Direct catalytic homoaldol reaction of ethyl pyruvate was performed using an(More)
[structure: see text] The configuration of the alpha-substituted alpha-hydroxy-beta-aminoester moiety in a series of 2'-substituted taxanes was analyzed according to the recently proposed Universal NMR Database (UDB) approach. A critical analysis of the results showed that modifications regarding chemical shift adjustment (so as to render the shifts(More)
