Recently I am researching about SILYL ETHERS; SELECTIVE DEPROTECTION; ALCOHOLS; PROTECTION; BIOCATALYSTS; RESOLUTION; CATALYSIS, Saw an article supported by the CNPqConselho Nacional de Desenvolvimento Cientifico e Tecnologico (CNPQ) [447110/2014-4]. Safety of 1-(4-Nitrophenyl)ethanone. Published in GEORG THIEME VERLAG KG in STUTTGART ,Authors: Brondani, PB; Mittersteiner, M; Voigt, MA; Klinkowski, BH; Scharf, DR; de Jesus, PC. The CAS is 100-19-6. Through research, I have a further understanding and discovery of 1-(4-Nitrophenyl)ethanone
Several commercially available lipases were examined in a study on O-Si bond formation and cleavage applying silicon-based protecting groups and alcohols or the corresponding silyl ethers. With regard to deprotection, from silyl ether to the corresponding alcohol, only the solvent and the lipase were necessary. The influence of the protecting group, the lipase source, and the substituent was investigated to optimize the results. The TMS moiety could be removed in 24 hours of reaction at room temperature in aqueous systems (conv. up to 99%, depending on the substrate and lipase). The reverse reactions, that is, with the protection of the alcohols, were carried out in hexane using different silyl chlorides. The TMS, TES, and TBS moieties were successfully inserted in the primary and secondary alcohols without the need for dry conditions or an inert atmosphere, presenting conversions of up to 99%, depending on the substrate.
