Binucleophilic biogenic alpha-aminoacids 1 such as cysteine, penicillamine, serine, and threonine react with lactam acetals 2 by condensation to bridged alpha-amidinoacids 3 or by condensation/ring transformation to 2-(omega-aminoalkyl)-1,3-azoline-4-carboxylic acids 6. Corresponding reactions with lactim ethers 7 afford analogous alpha-amidinoacids 8, condensed imidazolones 10 as their derivatives, omega-aminoalkyl-1,3-azolines 13 and, by further reaction with lactim ether 7, modified omega-amidinoalkyl-1,3-azolines 14.
