Synthetic Route of 86-55-5, New discoveries in chemical research and development in 2021.The transformation of simple hydrocarbons into more complex and valuable products via catalytic C–H bond functionalisation has revolutionised modern synthetic chemistry. 86-55-5, Name is 1-Naphthoic acid, SMILES is O=C(O)C1=C2C=CC=CC2=CC=C1, molecular formula is C11H8O2, belongs to thiomorpholine compound. In an article, author is Candela-Lena, Jose I., introduce new discover of the category.
Tandem conjugate addition of homochiral lithium N-benzyl-N-(alpha-methyl-p-methoxybenzyl)amide to tert-butyl cinnamate and enolate trapping with (TsSBu)-Bu-t proceeds with high diastercoselectivity to give a homochiral anti-alpha-tert-butylthio-beta-amino ester. Stepwise deprotection gives the corresponding free alpha-tert-butylthio-beta-amino acid without epimerisation. Tandem conjugate addition of homochiral lithium N-allyl-N-(alpha-methylbenzyl)amide to tert-butyl cinnamate and enolate trapping with TsS’Bu followed by conversion of the S-tert-butyl group to a disulphide, and reduction with Lalancette’s reagent generates polysubstituted thiomorpholine derivatives.
