SIAMYL GLYOXYLATE AS AN EFFICIENT ENOPHILE IN THE LEWIS-ACID MEDIATEDGLYOXYLATE ENE-REACTION WITH ALLYLIC ETHERS - APPLICATION TO THE SYNTHESIS OF A TAXOL A-RING SUBUNIT
J. Wennerberg et al., SIAMYL GLYOXYLATE AS AN EFFICIENT ENOPHILE IN THE LEWIS-ACID MEDIATEDGLYOXYLATE ENE-REACTION WITH ALLYLIC ETHERS - APPLICATION TO THE SYNTHESIS OF A TAXOL A-RING SUBUNIT, Journal of organic chemistry, 62(25), 1997, pp. 8735-8740
In contrast to other simple alkyl glyoxylates, siamyl glyoxylate (la)
proved to be an effective enophile in the glyoxylate ene-reaction with
the allylic ether 2a, which we earlier used for the synthesis of the
A-ring subunit of taxol.
