✦ Synopsis

Abatraa

: Inter-and Intramolecular Houben-Hoesch reactions have been used for the first time for the enantioselective synthesis of both the antipodes of 5,7-dimethoxy-2-methyl chroman-4-one.

(Rl-7-Methoxy-2methyl chroma&-one has been diastereoselectively elaborated to the dimethylchromanol moiety of calanolide A.

The chromaw4-one rirqg system occupies a prominent position among the heterocycies.

1977, 207-428.
