The o ‐hydroxyformylcoumarin 5b , easily prepared from compound 1 , is further transformed to the title coumarin derivatives 7, 10, 19a‐c via its initial Wittig olefination with ylides 2b, 8, 18a‐c respectively. Coumarins 16a, b were also formed by treatment of 5b with compounds 15a, b . The preparation of the interesting furocoumarin derivatives 11, 14, 20b, c as well as of compound 13 is also described.
