giving a range of new bis-homophenylalanine and related derivatives in good yields (9 examples, 53–64%). One of the Suzuki coupling products has been elaborated to give the N-Cbz-protected natural product pyrimine. The hydroboration–Suzuki coupling of vinylglycine derivatives was also studied but was less efficient than with the allylglycine derivatives: the best results were obtained using disiamylborane·DMS

been hydroborated and the intermediate organoborane employed in Suzuki coupling reactions with a number of olefinic, aromatic and heteroaromatic bromides and iodides to produce a range of novel α-aminoacids in good, unoptimised yields.
