One-Flask Syntheses of c-di-GMP and the [Rp,Rp] and [Rp,Sp] Thiophosphate Analogues
摘要:
An integrated set of reactions and conditions that allow an eight-step one-flask synthesis of the protected derivatives of c-di-GMP and the [R-p,R-p] and [R-p,S-p] thiophosphate analogues is reported. Deprotection is also carried out as a one-flask procedure, with the final products isolated by crystallization from the reaction mixture. Chromatography is only used for separation of the thiophosphate diastereomers.
