The present invention relates to methods for the synthesis and purification of cyclic nucleotide derivatives. The present invention provides a method for separating a cyclic nucleotide derivative from a mixture resulting from a chemical reaction to produce a cyclic nucleotide derivative from a cyclic nucleotide. In one embodiment, this mixture may comprise a cyclic nucleotide derivative, a pyridine solvent, and at least one of an alkyl carboxylic acid, an alkyl acid halide, or an alkyl carboxylic acid anhydride. In another embodiment, this mixture may comprise a cyclic nucleotide derivative and at least one of an alkyl carboxylic acid, an alkyl acid halide, or an alkyl carboxylic acid anhydride.

Studies on the synthesis of compounds related to adenosine 3',5'-cyclic phosphate. VII. Synthesis and cardiac effects of N6,N6-dialkyl adenosine 3',5'-cyclic phosphates.
A series of novel N6,N6-dialkyl adenosine3',5'-cyclicphosphates N6,N6-dialkyl cAMPs) was synthesized from 2'-O-p-toluenesulfonyl cAMP (2'-O-tosyl cAMP, 2) and tested for inotropic and chronotropic activities in vitro. Treatment of 2 with excess alkyl halides and sodium hydride followed by detosylation with aqueous NaOH readily gave N6,N6-dialkyl cAMPs (3) in good yields. Various N6,N6-dialkyl cAMPs

A stereospecific method for cyclising D-glucose 6-[16O,17O,18O]phosphate and adenosine 5′-[16O,17O,18O]-phosphate to their conformationally locked six-membered cyclic phosphate diesters has been developed. Using [16O,17O,18O]phosphateesters of known absolute configuration it is shown by 31P n.m.r. spectroscopy, after esterification to the axial and equatorial triesters, that the cyclisation occurs

used cardiovascular drug. The traditional batch synthesis process suffers from long reaction times, tedious operations, and unstable yields. Herein, a sequential continuousflowsynthesis combined with a multistage in-line purification process of calcium dibutyryladenosine cyclophosphate was developed. The acylation reaction was completed in a continuous coil reactor at 160 °C in 20 min. And the high
