Eudistomins L, K, C, E (30) and F (33) were synthesized from the corresponding N-hydroxytryptamine 21 and the D-cysteinal 23. A bromine of eudistomin L was biomimetically introduced onto the pyrroloindolic intermediate 8. Other eudistomins were prepared from substituted indoles 17. A modified Pummerer reaction was used to obtain the oxathiazepine ring.

Diaminoalkanes of Formula I have now been found which are orally active and bind to aspartic proteases to inhibit their activity. They are useful in the treatment or amelioration of diseases associated with elevated levels of aspartic protease activity. The invention also relates to a method for the use of the compounds of Formula I in ameliorating or treating aspartic protease related disorders in a subject in need thereof comprising administering to said subject an effective amount of a compound of Formula I.
Total synthesis of (−)-eudistomins with an oxathiazepine ring. Part 1. Formation of the oxathiazepine ring system
Formation of the oxathiazepine ring in eudistomins 1 was investigated. Thiazolidinyl-β-carboline 5 was successfully transformed into thiaindoloquinolizidine 7, but attempted oxidative transformation of 7 to 1 was not successful. The oxidative cyclization of 1-substituted-2 hydroxy-β-carboline 24 with NCS or the acid-catalyzed cyclization of the corresponding S-oxide 26 with TsOH gave oxathiazepine
