“…The absolute configuration of (S)-mandelonitrile acetate (2) was attributed by comparing the rotation signal measured with that reported in the literature. 15,16 Therefore, it is expected that the unreacted enantiomer 1 present R-configuration.…”

“…The spectroscopic data are in agreement with those reported in the literature. 15 (±)-Mandelonitrile (1) was purchased from SigmaAldrich and contained (less than 0.5%) benzaldehyde. Anhydride acetic, pyridine and benzaldehyde were purchased from Synth.…”

“…A configuração absoluta da (±)-mandelonitrila 1a obtida por resolução quimioenzimática foi determinada por comparação do sinal da medida de rotação óptica com a literatura (OGNYANOV et al, 1991;XU et al, 2008) -5,6 (c 0,58; CHCl3; ee 98,3%) (XU et al, 2008).…”

“…( Xu et al (2008) realizaram a resolução quimioenzimática de ciano-hidrinas aromáticas contendo diferentes grupos substituintes, possibilitando sintetizar moléculas biologicamente ativas. Nesse estudo foi utilizado como catalisador a lipase PS-30 e o acetato de vinila como agente acilante, obtendo-se excelentes conversões e excessos enantioméricos (Esquema 2.14, Tabela 2.5).…”
