Synthesis, Characterization and Computational Studies of Two Triazaspiro Tetracycles

Abstract

Two new triazaspiro tetracycles have been synthesized, the compounds have been characterized using spectroscopy, microanalysis and single crystal X-ray diffractometry. The single crystal X-ray crystallography of 4-methyl-8^I,10^I,17^I-triazaspiro[cyclohexane-1,9^I-teracyclo[8.7.0^2,7.0^11,16]heptadecane]-1^I(17),2^I(7^I),3^I,5^I,11^I,13^I,15^I-heptaene (compound I) has been discussed. The DFT computed bond angles have been obtained for both compounds and contrasted with experimental results for compound I. The atoms that make up the frontier orbitals which contribute to the reactivity of the compounds have been discussed.
