✦ Synopsis

Synthetic routes leading w the synthesis of rhe twwal I-a&y1 and I-phenyl coumartns isolatedfiom calophylhm sp. are reported. The reported s~rucmres of caianolides C and D and oblon@de are incorrect and have been correctid by unambtguous synthesis. Extraction of several tropical plants of the genus Calophyllum (Guttiferae) has over the last 30 years led to the isolation of coumarins of the general type (l-3).
