Rotameric properties of novel N-acyl and N-acyloxy dimeric 4-phenyl-1,4- dihydropridines derived from developed solid-state synthesis

Article abstract of DOI:10.3987/COM-99-8627

Novel N-acyl and N-acyloxy dimeric 4-phenyl-1,4-dihydropyridines are given by solid-state photodimerization of their monomeric educts in excellent yields. The existence of rotamers was demonstrated by ¹H NMR spectroscopical measurement at certa
