REGIO- AND SITE-SELECTIVE HETEROANNULATION REACTION PROMOTED BY m-CHLOROPERBENZOIC ACID ON 3-(1,3-DISUBSTITUTED 3-BUTEN-1-YL)-4-HYDROXYCOUMARINS. SYNTHESIS OF 3,4-DIHYDRO-2-HYDROXYMETHYL-2H,5H-PYRANOBENZOPYRAN-5-ONES

Epoxidation of 3-(1,3-disubstituted 3-buten-1-yl)-4-hydroxycoumarins, 1, bearing alkyl and aryl substituents with a slight molar excess of m-chloroperbenzoic acid gives 3,4-dihydro-2-hydroxymethyl-2H,5H-pyranobenzopyran-5-ones, 3, in medium to h

EPOXIDATION OF 3-(3'-BUTENYL)-4-HYDROXYCOUMARINS AND INTRAMOLECULAR 6-EXO CYCLIZATION TO 3,4-DIHYDRO-2-HYDROXYMETHYL-2H,5H-PYRANOBENZOPYRAN-5-ONES

Several 3-(3'-butenyl)-4-hydroxycoumarins were synthetized and oxidized with m-chloroperbenzoic acid. 3,4-dihydro-2-hydroxymethyl-2H,5H-pyranobenzopyran-5-ones were obtained through an intramolecular 6-Exo cyclization of intermediate epoxide.
