1,3-Dihalogenoprop-2-yl chloroformate and chloromethyl 1,3-dichloroprop-2-yl ether are used as versatile reagents for fluoroisopropenyl carbamylation and fluoroisopropenoxymethyl etherification, respectively.

The synthesis of acyclic analogues of ribo- and deoxyribonucleosides is described. These compounds (Table 3) are both poor substrates and poor inhibitors of adenosine deaminase. The synthesis of dinucleotides from these analogues is also described, and the activity along with the inhibitory properties of some of them are studied against deaminase enzyme. These nucleotides are resistant to degradation

The facile, high-yielding, yet general synthesis of electrophilic chloroacetone equivalents 11a-f is described. The enol ethers are assembled in three steps starting with trichloride 29 in overall yields of 57-93%. Nucleophilic displacement of the chloromethyl chlorine with a range of organometallic reagents generates dichlorides 30 in yields of 58-99%, which can be dehydrohalogenated with t-BuOK/THF in yields of 87-99% to produce enol ethers 31. Conversion of the allyl chlorides 31 to the corresponding allyl iodides 11 with 72-99% yield completes the synthetic sequence. The entire sequence can be performed in less than 48 h on a >50 mmol scale.
