tert-Butyl 5,6-dihydropyridine-1(2H)-carboxylate (cas: 85838-94-4) belongs to pyridine derivatives. Pyridine’s the lone pair does not contribute to the aromatic system but importantly influences the chemical properties of pyridine, as it easily supports bond formation via an electrophilic attack. Halopyridines are particularly attractive synthetic building blocks in a variety of cross-coupling methods, including the Suzuki-Miyaura cross-coupling reaction.Synthetic Route of C10H17NO2

Fast Olefin Metathesis at Low Catalyst Loading was written by Peeck, Lars H.;Savka, Roman D.;Plenio, Herbert. And the article was included in Chemistry – A European Journal in 2012.Synthetic Route of C10H17NO2 This article mentions the following:

Reactions of the Grubbs 3rd generation complexes [RuCl2(NHC)(Ind)(Py)] (N-heterocyclic carbene (NHC)=1,3-bis(2,4,6-trimethylphenylimidazolin)-2-ylidene (SIMes), 1,3-bis(2,6-diisopropylphenylimidazolin)-2-ylidene (SIPr), or 1,3-bis(2,6-diisopropylphenylimidazol)-2-ylidene (IPr); Ind = 3-phenylindenylid-1-ene, Py = pyridine) with 2-ethenyl-N-alkylaniline (alkyl = Me, Et) gave the new N-Grubbs-Hoveyda-type complexes 5 (NHC = SIMes, alkyl = Me), 6 (SIMes, Et), 7 (IPr, Me), 8 (SIPr, Me), and 9 (SIPr, Et) with N-chelating benzylidene ligands in yields of 50-75%. Compared to their, resp., conventional, O-Grubbs-Hoveyda complexes, the new complexes were characterized by fast catalyst activation, which translates into fast and efficient ring-closing metathesis (RCM) reactivity. Catalyst loadings of 15-150 ppm (0.0015-0.015 mol %) are sufficient for the conversion of a wide range of diolefinic substrates into the resp. RCM products after 15 min at 50° in toluene; compounds 8 and 9 are the most catalytically active complexes. The use of complex 8 in RCM reactions enables the formation of N-protected 2,5-dihydropyrroles with turnover numbers (TONs) of up to 58,000 and turnover frequencies (TOFs) of up to 232,000 h-1; the use of the N-protected 1,2,3,6-tetrahydropyridines proceeds with TONs of up to 37,000 and TOFs of up to 147,000 h-1; and the use of the N-protected 2,3,6,7-tetrahydroazepines proceeds with TONs of up to 19,000 and TOFs of up to 76,000 h-1, with yields for these reactions ranging from 83-92%. In the experiment, the researchers used many compounds, for example, tert-Butyl 5,6-dihydropyridine-1(2H)-carboxylate (cas: 85838-94-4Synthetic Route of C10H17NO2).
