“…Lipases have also been reported to display promiscuous aldolase activity [35,36] and recently asymmetric aldol reactions between acetone and 4-nitrobenzaldehyde (catalysed by porcine pancreas lipase) [37] and aromatic and heteroaromatic aldehydes with cyclic ketones (catalysed by chymopapain, nuclease p1, alkaline protease BLAP and acidic protease AUAP) [38,39] have been described. Care must, however, be taken since some of these apparent promiscuous activities have been shown to be due to a combination of the natural activity of the enzyme coupled with spontaneous chemical reaction with the other aldol partner to generate the misleading promiscuous activity (reviewed in [40]).…”

“…Procedimento: Em um balão de fundo redondo de 25 mL em agitação magnética a 30 ou 50 °C foram adicionados 5,5 mL de DMSO e H2O (7:3) como solvente. Posteriormente, foram adicionados o 4-nitrobenzaldeído (1,0 mmol), a cicloexanona (4 mmol) e a enzima avaliada (100 mg) (Li et al, 2010;Guan et al, 2012). A reação foi mantida por 5 dias e posteriormente foram adicionados 60 mL de acetato de etila e 30 mL de solução saturada de NaCl.…”

“…As reações realizadas em sistema reacional não convencional de A enzima RNL não apresentou bons rendimentos para as reações aldólicas entre a cicloexanona e aldeídos aromáticos em estudos da literatura empregando acetonitrila e água como meio reacional (Guan et al, 2012;Zheng et al, 2014) (Li et al, 2008), sendo utilizada para diversos aldeídos cíclicos e heterocíclicos em diferentes condições experimentais (Li et al, 2010;Guan et al, 2012;Zheng et al, 2014).…”
