synthesis of some new monocyclic β-lactams containing a quaternary carbon center via a [2+2]cycloaddition reaction is described. the reaction of achiral diphenyl ketene with chiral aldimines derivedfrom chiral 2, 3, 4, 6-tetra-o-acetyl-β-d-galactopyranosylamine, 2, 3, 4, 6-tetra-o-acetyl-β-dglucopyranosylamine and different benzaldehydes resulted in the formation of β-lactams as singlediastereo...
A nonlocal boundary value problem for the fractional version of Rayleigh–Stokes equation, well-known in fluid dynamics, is studied. Namely, condition u(x,T)=βu(x,0)+φ(x), where β an arbitrary real number, proposed instead initial condition. If β=0, then we have inverse time, called backward problem. It that ill-posed sense Hadamard. β=1, corresponding non-local becomes well-posed Hadamard, and ...
