SYNTHESIS AND STEREOCHEMISTRY OF EPIMERIC 3-BENZOYLTROPANES
Nemes, P.,Scheiber, P.,Kraiss, G.,Nador, K.
, p. 235 - 242 (2007/10/02)
Possible synthetic routes to prepare the epimeric 3-benzoyltropanes were investigated.Despite the use of 3α-substituted tropane derivatives as key precursors in attempts to obtain 3α-benzoyltropane (VIII), the formation of 3β-benzoyltropane (I) was mostly
