The synthesis of 4-aminocarbonylmethoxy trinems was accomplished through Lewis acid catalysed opening of an epoxide intermediate with allyl glycolate, followed by deallylation, activation of the free acid via the 2-pyridyl thiolester and reaction with a series of trimethylsilylamines. An alternative route involving a rhodium-catalysed diazoacetate insertion was also successfully exploited. (C) 1997 Elsevier Science Ltd.
