Aoki et al. also studied the hydrolysates of cyclothiazomycin (3) in their paper describing its structural elucidation. However, they isolated this unit in lactam form despite almost identical degradation conditions. The reason for these differences is unclear.

Prior to the chemical shift predictions, structural optimization was performed employing ab initio 6-31G* for each model compound. We used Spartan '04 program by Wavefunction Inc. (18401 Von Karman Avenue, Suite 370 Irvine, CA 92612).

The theoretical chemical shifts predictions suggested the olefinic protons of (E)-DHHA residues appear ca. 1.0 ppm lower field than that of the corresponding (Z)-DHHA residues for other model compounds as shown below. These calculations also indicated that (Z)-DHHA residues are ca. 2.5 kcal/mol sterically more stable than the (E)-DHHA residues. These results also are consisent with our assumption for the stereochemistry of DHHA2 moiety in 1 and 2.

+. These indicated the same mass number 1472, whereas the mass formula by Cooper was one carbon smaller than that of Aoki's 3. Cooper also disclosed existences of a dehydroalanine, two dehydrohomoalamnines, three thiazolines, and three thiazoles, which are the same residues as those involved in Aoki's 3. Physical properties of our 1 and 2 were rather similar to those in Copper's report: Cooper, R.; Truumees, I.; Barrett, T.; Patel, M.; Schwartz, J.; Puar, M.; Das, P.; Pramanik, B. J. Antibiot. 1990, 43, 897.
