The isolation and structure of leptosphaerin : a metabolite of the marine ascomycete, Leptosphaeria oraemaris (Linder) and A synthesis of the marine toxin, 9-isocyanopupukeanane

Creator:: Schiehser, Guy Alan
Abstract:: The ethyl acetate extract of the culture filtrate of the marine Ascomycete, Leptosphaeria oraemaris (Linder) yielded a novel metabolite designated by the common name leptosphaerin. An x-ray crystallographic structure analysis was disproved by the synthesis of 3-acetoxy-S-(1,2-dihydroxyethyl)- 3-pyrrolin-2-one 1, starting with N,N-dibenzylhydroxylamine 47 and D-mannitol 44. Oxidation of 47 followed...

Water and methanol adsorption on a series of organic complexes of montmorillonite

Creator:: Carter, Loren Sheldon
Abstract:: Water and methanol adsorption isotherms at 25° and 37° C. were determined on a series of organo-bentonite clays. The clays differed in the length of the carbon chain attached to the amine adsorbed in the cation exchange position. The amines used had carbon chains of 4, 6, 8, 10, 12,...

A Chemical Study of Western Oregon Nutgalls

Creator:: Johnson, Clarence William and De Haven, Glen
Abstract:: Few discoveries of any importance have been the result of a moment's happy coincidence; rather have they been the fruit of many hours of tedious thought and experiment. This is especially true in the realm of organic chemistry. Here, where progress is made only by the most painstaking experimentation, extensive...
