摘要：

Formal synthesis of ethisolide and iso-avenaciolide was achieved using furanoid glycal-vinyl radical intermediates. The vinyl radical cyclization by 5-exo-dig mode gave the cis-fused bicyclic systems with an efficient introduction of the exo-methylene group, besides helping in the inversion of the adjacent stereocentre. Further, the study describes the synthesis of cis-fused bicyclic systems from L-arabinose and D-xylose for the creation of diverse natural and synthetic products of this class.
