In 2019,Journal of the American Chemical Society included an article by Bahamonde, Ana; Al Rifaie, Buthainah; Martin-Heras, Victor; Allen, Jamie R.; Sigman, Matthew S.. Electric Literature of C5H11NO2. The article was titled 《Enantioselective Markovnikov Addition of Carbamates to Allylic Alcohols for the Construction of α-Secondary and α-Tertiary Amines》. The information in the text is summarized as follows:
In the presence of Pd(MeCN)2(OTs)2 and a nonracemic pyridinyloxazoline, trisubstituted allylic alcs. such as I or (Z)-disubstituted allylic alcs. underwent regioselective and enantioselective addition and isomerization reactions with benzyl and tert-Bu carbamates to yield (after aldehyde reduction with NaBH4) protected secondary and tertiary β-amino alcs. such as II. Three of the β-amino alcs. were oxidized to β-amino acids with little loss of enantiopurity. Reaction of a dideuterated allylic alc. indicated that C-N bond formation occurs by syn-aminopalladation. In the part of experimental materials, we found many familiar compounds, such as tert-Butyl carbamate(cas: 4248-19-5Electric Literature of C5H11NO2)
tert-Butyl carbamate(cas: 4248-19-5) belongs to anime. In organic chemistry, amines are compounds and functional groups that contain a basic nitrogen atom with a lone pair. Amines are formally derivatives of ammonia (NH3), wherein one or more hydrogen atoms have been replaced by a substituent such as an alkyl or aryl group (these may respectively be called alkylamines and arylamines; amines in which both types of substituent are attached to one nitrogen atom may be called alkylarylamines).Electric Literature of C5H11NO2
