Abstract
A short, concise synthesis of queuine was accomplished in a 36% overall yield through a convergent scheme utilizing a reductive amination as the penultimate step. The synthesis demonstrates the utility of silylation to facilitate reactions of various pyrrolo[2,3-d]pyrimidine intermediates, and offers the possibility of easily accessing related pyrrolo[2,3-d]pyrimidines as well as making additional analogues of queuine.
