Welsh, Erin N. published the artcileShort syntheses of 1-substituted dibenzothiophene derivatives, Application of (S)-2-Methylpropane-2-sulfinamide, the main research area is dibenzothiophene preparation.
A simple one-pot preparation of 1-lithiodibenzothiophene from com. materials via a cascade of two benzyne additions and conversion to several derivatives I (R = I, CHO, CN, C(O)CF3, etc.) by addition of electrophiles (N,N-dimethylformamide, benzaldehyde, 1-propanal, etc.) was demonstrated. A chiral amine containing the 1-dibenzothiophenes motif II (R1 = H, (S)-S(O)C(CH3)3; R2 = Me, Et) was also prepared This work avoids the use of precious metals or tert-butyllithium and is much shorter and more convenient than existing routes to 1-substituted dibenzothiophenes I.
Organic & Biomolecular Chemistry published new progress about Addition reaction. 343338-28-3 belongs to class amides-buliding-blocks, name is (S)-2-Methylpropane-2-sulfinamide, and the molecular formula is C4H11NOS, Application of (S)-2-Methylpropane-2-sulfinamide.
