Total syntheses of (+)-polygalolide A and (+)-polygalolide B: Elucidation of the absolute stereochemistry and biogenetic implications

The total syntheses of (+)-polygalolide A and (+)-polygalolide B have been completed by using a carbonyl ylide cycloaddition strategy. Three of the four stereocenters, including two consecutive tetrasubstituted carbon atoms at C2 and C8, were incorporated

Total synthesis and absolute stereochemistry of polygalolides A and B

(Chemical Equation Presented) Carbonyl ylides to the fore: the first total synthesis of polygalolides A (1) and B (2) has been achieved by exploiting a tandem carbonyl ylide formation/1,3-dipolar cycloaddition to construct the unprecedented 5,10-dioxatric

Structure-activity relationship for DNA topoisomerase II-induced DNA cleavage by azatoxin analogues

Eighteen analogues of the nonintercalative DNA topoisomerase II (topo II)-active epipodophyllotoxin-ellipticine hybrid, azatoxin, were synthesized and evaluated for their ability to induce topo II-mediated DNA strand breaks in vitro. In general, the SAR p

Inhibition of DNA topoisomerase II by azaelliptitoxins functionalized in the variable substituent domain

A series of novel C11-substituted derivatives of azaelliptitoxin (azatoxin) have been synthesized and tested for their inhibitory activity against human DNA topoisomerase II. Incorporation of a C11 polyamine or amine resulted in an i

Esters are effective co-catalysts in copper-catalyzed methanolysis of aryl bromides

Rate of copper(I)-catalyzed substitution of aryl bromides into methyl-aryl ethers by methoxide ion is greatly enhanced in presence of esters. Soluble copper(I) complexes 2, arising from tetrahedral adducts 1 of methoxide onto esters, are likely responsible for this improvement.
