Synthesis

4-(9>-cyclopentyl-5'-methyl-6>-oxo-5>,6>,8>,9>- tetrahydrospiro[cyclobutane-l,7'-pyrimido[4,5-b][l,4]diazepine]-2'-ylamino)-3- methoxybenzoic acid; [0521] Ethyl 1-cyanocyclobutanecarboxylate; To a solution of sodium ethoxide (21wt% in EtOH, 5.79 rnL, 15.5 mmol) in EtOH (25 mL), was added ethyl cyanoacetate(1.12 mL, 10.5 mmol), followed shortly thereafter by 1,1-dibromopropane (1.12 mL, 10 mmol). The reaction mixture was refluxed for 3 hrs. It was then concentrated, and diluted to ethyl acetate. The organic layer was washed with NaHCCh, brine, water, dried over Na2SO4 and concentrated in vacuo to obtain ethyl 1-cyanocyclobutanecarboxylate (1.17 g, 74% yield) as a red liquid. It was used directly for next step reaction.

Synthesis of the First Representatives of Spiro-1λ6-isothiazolidine-1,1,4-triones

A strategy for the construction of spiro[cycloalkane-1,3′-1′λ6-isothiazolidine]-1′,1′,4′-triones through the sulfonylation of 1-aminocyclopropane- and 1-aminocyclobutanecarboxylates with methanesulfonyl chloride followed by alkylation with methyl iodide and subsequent cyclization in the presence of potassium tert-butoxide in N,N-dimethylformamide is reported.

Anionic ring-opening polymerization of alkyl 1- cyanocyclopropanecarboxylates

Poly(alkyl 1-cyanotrimethylene-1-carboxylate)s (CH2CH 2C(CN)(COOR))n are the next higher chain homologues of poly(α-cyanoacrylate)s. They were synthesized via the anionic ring-opening polymerization of the corresponding alkyl 1-cyanocyclopropanecarboxylate monomers initiated with thiophenolate salts (PhSM, with M = Li, Na, K, and NBu4) and at temperatures above 50°C. Precipitation of the growing polymer chains at an early stage during the polymerization did not prevent further propagation, probably via polymerization in the solid or at the solid surface. The propagating cyanoacetate carbanion is very stable in a normal air atmosphere, surviving for long periods of time in the absence of strong acids. Although monodisperse polymers were obtained in most experiments (M w/Mn + and NBu 4+ counterions were used. Nonquantitative initiations characterized polymerizations initiated by PhSLi and PhSNa. Attempted polymerizations of ethyl 1-cyanocyclobutanecarboxylate failed under similar or slightly more energetic experimental conditions, with the thiophenolate initiator attacking the pendant ester rather than the cyclic methylene group.
