Elaboration of the side chain of α-amino acids containing a vinyl iodide by palladium-catalysed coupling
摘要:
The palladium-catalysed coupling of a gamma-iodoallylglycine derivative and an E-delta-iodoallylglycine derivative with various organic nucleophiles is described.
Synthesis and transformations of trialkylstannyl-substituted allylglycine derivatives.
摘要:
The three racemic vinylstannyl allylglycine derivatives (1, E-2, Z-2) were prepared by a variety of hydrostannation reactions. These vinylstannanes were converted to the corresponding vinyl iodides (7, E-8, Z-8) by electrophilic iodination and to symmetrical 1,3-dienes (5, 6) by copper catalysed coupling. A cis-bis(trimethylstannyl)allylglycine derivative (cis-4) was also prepared by palladium catalysed addition of hexamethylditin.
