Chemistry of enol silyl ethers. A general synthesis of 3-hydroxyhomophthalates and a biomimetic synthesis of sclerin

Brownbridge, P.,Chan, T. H.,Brook, M. A.,Kang, G. J.

, p. 688 - 693 (2007/10/02)

A general synthesis of 3- hydroxyhomophthalates is developed and applied to the synthesis of sclerin (24), a compound possessing plant-growth activity; the critical step in the synthesis of 24 can be considered as the controlled condensation of a di-β-carbonyl unit with a tri-β-carbonyl unit.
