“…First, the acylglycines N -benzoylglycine ( 13 ), N -4-nitrobenzoylglycine ( 14 ), N -4-methoxybenzoylglycine ( 15 ), N -acetylglycine ( 16 ), and N -methoxycarbonylglycine ( 17 ) were synthesized under stricter pH control conditions. Syntheses of 13 , 14 and 16 have been already described in the literature. − 17 was synthesized with a 95% yield, improving the reported yield (66%) for its analogous N -ethoxycarbonylglycine using the starting products glycine and methoxycarbonyl chloride with an equimolecular mixture of NaOH/Na 2 CO 3 . 15 was synthesized in a manner similar to that used for 17 , using a basic blend of NaOH/Na 2 CO 3 at 0 °C with glycine and 4-methoxybenzoyl chloride.…”

Experimental and Theoretical Study of a New Class of Acceptor Group in Chromophores for Nonlinear Optics: 2-Substituted 4-Methylene-4H-oxazol-5-ones

Push−pull organic molecules that combine a polyfunctionalized electron-donating carbazole moiety with a new acceptor group, 4-methylene-4H-oxazol-5-ones, were synthesized and characterized as nonlinear optical chromophores with promising μβ values. First-order hyperpolarizability and dipole moments were calculated by MNDO, AM1 and PM3 methods. Theoretical μβ values were compared to experimental data measured in solution by electric-field-induced second-harmonic generation (EFISH). The different factors that could influence the NLO response, especially the gain or loss of aromatization stabilization during the charge-transfer process, were studied. The thermal stability of these new chromophores is also reported.
