HETEROCYCLES IX. ASYMMETRIC EPOXIDATION OF A QUINONE AND SYNTHESES OF CHIRAL LACTONES

The epoxy diketone (2) is obtained in optically active form by the phase-transfer chiral epoxidation of the quinone (1).The transformation of 2 to the lactones (5) and (6) is carried out without the loss of optical activity.

HETEROCYCLES. XI. SYNTHESES OF ANALOGS OF 10b-HYDROXYCHELIDONINE AND 4b-EPICHELIDONINE

The naphthoquinonine epoxide (4), derived from the naphthoquinonine (1), is reduced with sodium borohydride under mild conditions to yield the cis-epoxy ketol (5) exclusively.The configuration of the 4-hydroxyl group in 5 is deduced on the basis of the in
