The occurrence of C29 sterols with different configurations at C-24 in Cucurbita Pepo as shown by 270 MHz NMR

Wolfgang Sucrow; Marion Slopianka; Henry W. Kircher

Abstract The 270MHz NMR spectra of the major sterols of pumpkin seeds show that the configuration at C-24 of 24-ethyl-5α-cholesta-7,22,25-trien-3β-ol and 24-ethyl-5α-cholesta-7,25-dien-3β-ol is 24β F = (24 S ) whereas the α-spinasterol has the 24α F = (24 S ) configuration.

Thiocarbonyl Olefination III1: A New Synthesis of β-Aminoacids from N-Thioacylurethanes

Marion Slopianka; Albert Gossauer

Abstract It has been shown recently in our laboratory1 that the reaction of ethyl N-thioacylurethanes (2) with resonance-stabilized phosphorus ylides yields 3-(ethoxycarbonylamino) acrylic acid homologues (3) which may be converted, on hydrolysis, into alkyl β-oxocarboxylates.
