A DNMR STUDY OF ISOMERIC PHENOLS OBTAINED BY RING-OPENING, RING-CLOSURE OF 3-ISOPROPYL-2,4,6-TRIMETHYLPYRYLIUM SALTS: AN APPROACH TO THE REGIOSELECTIVITY OF THE RING-CLOSURE

The regioselectivity of the syntheses of phenols via dissymmetrical pyrylium salts is found to be related to the difference in steric strain in the products as determined by conformational analysis.

Two new syntheses of phenols have been developed which have been utilized in an efficient preparation of the antimicrobial-cytotoxic agent juncusol (22) and several members of the effusol (23) class of phenols.These results complement our earlier studies with enynones of type 42 and provide for the highly efficient conversion of 42 to either methylenecyclopentenones 45 or phenols of type 47 or 54 with virtually 100percent selectivity.
ENYNONES IN ORGANIC SYNTHESIS. III. A NOVEL SYNTHESIS OF PHENOLS

Enynones are converted to phenols by an acid catalyzed process which can be controlled to give either of two regioisomeric series of products.
