The sodiation of substituted acrylonitriles and alkenyl sulfides in a continuous flow set-up using NaDA (sodium diisopropylamide) in EtNMe2 or NaTMP (sodium 2,2,6,6-tetramethylpiperidide)?TMEDA in n-hexane provides sodiated acrylonitriles and alkenyl sulfides, which are subsequently trapped in batch with various electrophiles such as aldehydes, ketones, disulfides and allylic bromides affording functionalized acrylonitriles and alkenyl sulfides. This flow-procedure was successfully extended to other acrylates by using Barbier-type conditions.

To identify novel potent cardiac myosin activator, a series of diphenylalkylisoxazol-5-amine compounds 4–7 have been synthesized and evaluated for cardiac myosin ATPase activation. Among the 37 compounds, 4a (CMA at 10 μM = 81.6%), 4w (CMA at 10 μM = 71.2%) and 6b (CMA at 10 μM = 67.4%) showed potent cardiac myosin activation at a single concentration of 10 μM. These results suggested that the introduction of the amino-isoxazole ring as a bioisostere for urea group is acceptable for the cardiac myosin activation. Additional structure–activity relationship (SAR) studies were conducted. Para substitution (-Cl, –OCH3, -SO2N(CH3)2) to the phenyl rings or replacement of a phenyl ring with a heterocycle (pyridine, piperidine and tetrahydropyran) appeared to attenuate cardiac myosin activation at 10 μM. Additional hydrogen bonding acceptor next to the amino group of the isoxazoles did not enhance the activity. The potent isoxazole compounds showed selectivity for cardiac myosin activation over skeletal and smooth muscle myosin, and therefore these potent and selective isoxazole compounds could be considered as a new series of cardiac myosin ATPase activators for the treatment of systolic heart failure.

In a modification of the Wierenga-Skulnick β-ketoester synthesis, the dianions of malonic acid mono-amides were condensed with acid chlorides. Acidic workup led to decarboxylation and isolation of the corresponding β-keto amides in good-to-excellent yield
