Tj. Murray et al., SYNTHESIS OF HETEROCYCLIC-COMPOUNDS CONTAINING 3 CONTIGUOUS HYDROGEN-BONDING SITES IN ALL POSSIBLE ARRANGEMENTS, Tetrahedron, 51(2), 1995, pp. 635-648
The synthesis of compounds containing three contiguous hydrogen bond s
ites is reported. There are six ways of arranging three adjacent hydro
gen bond donor (D) and acceptor (A) sites. General synthetic routes to
heterocyclic compounds with each arrangement is reported.
