Stille-Vogel bismethoxycarbonylation of a series of norbornene-type mo
noenes, 9-15, and nonconjugated dienes, 16 and 17 was studied. Three s
ignificant findings ate: (1) Bismethoxycarbonylation reactions may be
carried out using CO at atmospheric pressure. (2) The sensitive p-meth
oxybenzyl protecting group withstands the Stille-Vogel reaction condit
ions. (3) The bismethoxycarbonylation reaction may be carried out usin
g THF as a cosolvent, although reaction times are longer.
