  Solid-phase based synthesis of biologically promising triazolyl aminoacyl (peptidyl) penicillins

  摘要：

  An efficient and versatile methodology for the preparation of valuable triazolyl aminoacyl (peptidyl) penicillins is described. Solid-phase Cu(I)-catalyzed Huisgen 1,3-dipolar cycloaddition was used as the key step showing general applicability and excellent regioselectivity either with CuI or [Cu(CH3CN)(4)]PF6 as Cu(I) source.

  6-dihalo-, 6β-halo-penicillanates, 6,6-dihalopenam derivatives and (1S)-6-α-halopenicillanates sulfoxides by dimethyldioxirane asymmetric oxidation of the corresponding penicillanates and penam derivatives. This method is characterized by mild reactions conditions, short reaction times, excellent selectivity, very high yield, ease of reaction workup and complete avoidance of overoxidation products.
