ene-type reactionmethyl β-alkenylsulfinatesLewis acidscatalytic effectTrisubstituted methylalkenes react with methyl sulfite at 25°C in the presence of BF 3 · Et 2 O in the ene-type fashion to give the corresponding methallyl sulfinates. Such compounds can also be prepared under considerably ...
Fig. 1: Transition metal-catalyzed Alder-ene type reaction. All-carbon chiral quaternary stereocenters are fundamental structural motifs present in natural products and pharmaceuticals, which could improve the metabolic stability and target selectivity of biologically active compounds30. However, the synthesi...

In this work we wish to report that the Pummerer-type reaction intermediate derived from methyl α-( methylthio)acetate and phenyliodine(III) bis(trifluoroacetate) (PIFA) undergoes an ene reaction with 1-alkenes to give the ene adductsand its application to the synthesis of Achillea amide. 展开...
The hydroxyketone derivative 3 was obtained by bromination of 2 and subsequent reaction with NaOH in decent yield of 61% [23]. This compound was used as a precursor molecule for the synthesis of the photoinitiators PI-4, Conclusion In this contribution, alkyne functionalized hydroxyalkylphenone...
Cysteines were reduced using DTT (10 mM) in NH4HCO3 (100 mM) for 30 min followed by an alkylation reaction using iodoacetamide (55 mM) in NH4HCO3 (100 mM) for 20 min. Afterwards, samples were washed with NH4HCO3 (100 mM) and subsequently dehydrated with 100% (v/v) ACN. Trypsin (6 ...
