摘要：

The mass spectra of columbianetin and its acetate, angelate, tiglate, and 3‐bromo‐angelate have been determined. Columbianetin shows M →188 →187 (base peak 187) as the principal fragmentation pathway whereas the esters show M → 228 → 213 (base peak 213) as the major fragmentation route. Probable mechanisms for fragmentation are suggested. Copyright © 1968 Wiley‐Liss, Inc., A Wiley Company
