Abstract

Abstract Stereoselective syntheses of 1, 6-bis (tributylstannyl) hexa-1, 3, 5-trienes, 1, 8-bis (tributylstannyl) octa-1, 3, 5, 7-tetraenes, and 1, 10-bis (tributylstannyl) deca-1, 3, 5, 7, 9- pentaenes with various methylation patterns were achieved based on stereocomplementary C [DOUBLE BOND] C bond-forming reactions. All-E isomers resulted from Ramberg– Bäcklund rearrangements of distannylated diallyl-, allylpentadienyl-, or bis-(pentadienyl) ...
