N. Matsumura et al., Synthesis of novel macrocyclic compounds utilizing characteristic bonding properties of hypervalent sulfur, HETEROCYCLE, 53(6), 2000, pp. 1239-1245
The convenient method for the synthesis of 18-, 26-, and 30-membered macroc
yclic compounds by utilizing the characteristic bonding properties of the h
ypervalent sulfur in the 10-S-3 tetraazathiapentalene derivatives and their
chemical properties have been described. The structures were established b
y their spectral data and X-Ray crystallographic analysis.
