Abstract

Abstract The 121.5 MHz 31P NMR was used for elucidating kinetically the way the three basic bricks of the B.A.S.I.C. game are built. The formations of these three bricks obey second-order rate laws. The SPIRO loop is formed much faster than BINO bridge or ANSA arch. The 1,3-diaminopropane behaves as a genuine primary mono-amine. Kinetic data can be expressed in terms of very simple geometrical parameters such as ‘stability or not’ of the n-membered cyclic structures.
