Synthesis of some novel hydrazono acyclic nucleoside analogues

The syntheses of novel hydrazono acyclic nucleosides similar to miconazole scaffolds are described. In this series of acyclic nucleosides, pyrimidine as well as purine and other azole derivatives replaced the imidazole function in miconazole and the ether

Reaction of 7-(2-mesyloxy-2-phenylethyl)theophylline with amines: Synthesis of 1,2,3,6-tetrahydro-6-imino-2-oxo-7H-purine derivatives

Theophylline was converted to 7-(2-phenyl-2-methanesulfonyloxy)ethyl congener and the product was treated with ammonia or primary amines in a mixture solution of water and organic solvents. Two products were proven to be the styrene analogue and 7-(2-amino-2-phenylethyl)theophylline. The structure of the third product was elucidated as the 1,2,3,6-tetrahydro-6-imino-2-oxo-7H-purine derivatives by spectroscopic analysis including HMBC correlation and X-ray crystallography.

Generation and Properties of N7-Xanthinium Ylides: Reactions of N7-Xanthinium Ylides with Diphenylcyclopropenone and Acetylenic Compounds

Xanthinium N7-ylides were generated in situ from 7-substituted 9-methylxanthinium tosylates (2) using n-BuLi in tetrahydrofuran or Et3N in MeCN.The xanthinium N7-ylides (3) generated using Et3N in MeCN reacted with diphenylcyclopropenone to give pyrone derivatives and isocaffeine in good yields.The reactions of 3a-b with dimethyl acetylenedicarboxylate or methyl propiolate (MP) afforded 5-pyrrol-1-yluracils in moderate yields.N7-Methoxycarbonylmethylide (3c) reacted with MP to give a pyrrolopteridine derivative together with a 5-pyrrol-1-yluracil derivative.Furthermore, the dihydropyrrolopurine derivative (7) , a primary 1,3-dipolar cycloaddition product, was detected by nuclear magnetic resonance measurement of the products.Keywords - xantinium N7-ylide; cycloaddition; dimethyl acetylenedicarboxylate; methyl propiolate; diphenylcyclopropenone; 5-pyrrol-1-yluracil; pyrrolopteridine; isocaffeine
