Individual scheme managers who consented for their scheme to take part in the study were asked for permission to approach scheme residents as potential participants.
In [10], the author proposed a fuzzy logic CAC approach scheme for long-term evolution (LTE).
In the first approach (Scheme 3), the melamine and benzamidine moieties were attached via a triazole ring using click chemistry.
In the first approach (Scheme 48), diols 162 are reacted with PCl3 to yield the cyclic intermediate saligenylchlorophosphane 163.
The sensor was synthesized using the traditional radical polymerization approach (Scheme 1) with the co-polymerization of Rhod-MA, GS-MA, HPMA and MAETMA in DMF.
These observations encouraged us to prepare additional substituted aryl pyrazole analogues, which could be accessed by following either of two general synthetic approaches (Scheme 2).
While our first approach (Scheme 2) is more direct and higher yielding, the alternative route (Scheme 3) also provides the additional benefit of freeing the hydroxyl group at C-2 on the sugar residue (compound 10).
Our approach (Scheme 1) features a highly selective TA-mediated reductive amination of an achiral 1,4-diketone to generate an optically active pyrroline followed by diastereoselective chemoenzymatic conversion into the corresponding pyrrolidine by MAO-N/NH3⋅BH3.
Challenging substrates containing piperidine, morpholine, thiomorpholine, and piperazine moieties readily participate in this unprecedented α,β-difunctionalization. Notably, this reaction can also be performed as a three-component reaction, using a one-pot, two-stage approach (Scheme 14).
Since whole cells were used in this transformation, the hydratase activity needed to be critically evaluated.[ 11]–[ 14] Instead of a direct addition of water, the conversion of 1 a to 2 a could also occur via a two-step approach (Scheme Scheme 1).
In 2005, MacMillan and co-workers reported a combination of transfer hydrogenation using Hantzsch ester and electrophilic fluorination using NFSI on enal substrates, which would allow the formal asymmetric addition of HF across trisubstituted olefin systems using a cascade-catalysis approach (Scheme 40).
