THE INTERMOLECULAR BETA-COUPLING OF CYCLIC ENONES WITH ACTIVATED ALKENES AND ALKYNES - UNEXPECTED BETA-ALKOXY ELIMINATION FROM A 4-ALKOXY-2-ALKYL-1-HYDROXY-CYCLOPENTENYL RADICAL
G. Pandey et al., THE INTERMOLECULAR BETA-COUPLING OF CYCLIC ENONES WITH ACTIVATED ALKENES AND ALKYNES - UNEXPECTED BETA-ALKOXY ELIMINATION FROM A 4-ALKOXY-2-ALKYL-1-HYDROXY-CYCLOPENTENYL RADICAL, Tetrahedron letters, 39(45), 1998, pp. 8341-8344
Intermolecular beta-coupling of cyclic enones with activated alkenes o
r alkynes and an unexpected beta-alkoxide elimination from 17 during t
he extension of this strategy towards the synthesis of optically pure
prostaglandin analogues by the coupling of 16 and 11 is reported. (C)
