Fourier transform 13C nuclear magnetic resonance studies of steroids. Part I. Some substituted 17β-(2,5-dihydro-5-oxo-3-furyl) steroids
Abstract
The natural abundance 13C n.m.r. spectra of several substituted (2,5-dihydro-5-oxo-3-furyl) steroids, having hydroxy-groups at various positions in the steroid nucleus, have been measured. The effects of changes in the structure of the steroid nucleus upon substituent chemical shifts are evaluated and discussed.
