Stereoselective synthesis of: E -3-(arylmethylidene)-5-(alkyl/aryl)-2(3 H)-furanones by sequential hydroacyloxylation-Mizoroki-Heck reactions of iodoalkynes

A modular, stereoselective synthesis of E-3-(arylidene)-5-(alkyl/aryl)-2(3H)-furanones was developed. The methodology features regioselective addition of β-aryl acrylic acids to iodoacetylenes to furnish the Z-acyloxy iodoalkenes. A stereoselective 5-exo-trig Mizoroki-Heck reaction of the acyloxy iodoalkenes generates the target E-2(3H)-furanones. The approach was applied in a formal synthesis of the naturally occurring kinase inhibitor BE-23372M.

BE-23372M, a novel protein tyrosine kinase inhibitor. III. Synthesis

In a preceding paper, the physico-chemical properties and structural elucidation of BE-23372M, a potent novel protein tyrosine kinase inhibitor, were described. In this paper, we report the synthesis of BE-23372M from 3-(3,4-dimethoxybenzoyl)propionic aci
