Amides and amines play a central role in the control and modulation of virtually all biological processes. On the other side the inflexibility of the quaternary carbon of spirocycles locks the adjoined ring into a fixed 3-dimensional conformation such that it must receive some responsibility for its interaction with given receptors. Currently we have engaged ourselves in project aimed to define a one-pot protocol for the synthesis of highly functionalized spiro-oxindoles starting from corresponding a,b-enones, N-protected isatins andproline as well. We chose to synthesise the indolin-3 containing spirocycle, which provide a template for use in combinatorial chemistry. We have been able to demonstrate the versatility of 4a,b by derivatising the scaffold at each of its functional groups by use N-protected isatin 1, proline 2, and a,b-enones.formulaIn this report we demonstrate the stereoselectivity of [2+3] addition and crystal structure of two main products obtained by single crystal X-ray method.formulaCompounds 4a and 4b crystalize in centrosymmetric space groups, thus represent racemats. Space group and unit cell parameters for 4a are P-1, a=9.8449(7) b=12.552(1) c=12.6961(9)Å, a=115.561(8), b=97.134(6), z=101.279(7)º, V=1348.9(2)Å3 and for 4b P21/n,a=11.6456(7), b=11.6090(5), c=22.6398(9) Å, b =93.820(4)º, V=3054.0(2) Å3. |
