AbstractLet LSC(X) denote the set of extended real valued lower semicontinuous functions on a metrizable space X. If f, f1, f2, f3,... is a sequence in LSC(X), we say 〈fn〉 is epi-convergent to f provided the sequence of epigraphs 〈epi fn〉 is Kuratowski- Painlevé convergent to epi f.

Preparation of 3-epi-ecdysone and 3-epi-20-hydroxyecdysone
Steroids, 19783-Dehydro-ecdysone and 3-dehydro-20-hydroxyecdysone were prepared and characterized. Reduction of these compounds with NaBH4 gave 3-epi-ecdysone and 3-epi-20-hydroxyecdysone, which were characterized fully by mass and p.m.r. spectrometry as well as by derivative formation.

The stereospecific synthesis of leukotriene A4 (LTA4), 5-epi-LTA4, 6-epi-LTA4 and 5-epi,6-epi-LTA4
Tetrahedron Letters, 1981The stereospecific syntheses of the four isomers of 6-formyl-5,6-epoxy hexanoic acid methyl ester 8, 15, 23 and 30 from Z-deoxy-D-ribose have allowed the preparation of methyl esters of LTA4, 1, and its three unnatural isomers.

Total syntheses of (+)-2,8,8a-tri-epi-swainsonine and (-)-1-epi-swainsonine
The Journal of Organic Chemistry, 1993Parallel syntheses of the title swainsonine-related enantiomers 9 and 15 were achieved in five steps and in 55% overall yield via enantiomeric threose N-benzylimines 4 and 10, derived from L- and D-tartaric acid, respectively. A stereospecific 4 + 4 homologative procedure using 2-(trimethylsiloxy)-furan (TMSOF), obtained from 2-furaldehyde, was ...

[Cross-Linking in Keratoconus: "Epi-off" or "Epi-on"?].
Klinische Monatsblatter fur Augenheilkunde, 2016Corneal cross-linking can halt the progression of keratoconus, but what is the best approach for treatment? There are a number of treatment options for keratoconus, but only corneal cross-linking (CXL) appears to halt the progression of the disease. To guarantee effective cross-linking, CXL treatment involves removal of the corneal epithelium prior to ...
