In a Article，once mentioned of 40191-32-0, Product Details of 40191-32-0

The heterospirocyclic N-methyl-N-phenyl-2H-azirin-3-amines (3-(N- methyl-N-phenylamino)-2H-azirines) 1a-d with a tetrahydro-2H-pyran, tetrahydro-2H-thiopyran, and a N-protected piperidine ring respectively, were synthesized from the corresponding heterocyclic 4-carboxamides 2 by consecutive treatment with lithium diisopropylamide (LDA), diphenyl phosphorochloridate (DPPCl), and sodium azide (Scheme 4). The reaction of these aminoazirines with thiobenzoic acid in CH2Cl2 at room temperature gave the thiocarbamoyl-substituted benzamides 13a-d in high yield. The azirines 1a-d were used as synthons for heterocyclic alpha-amino acids in the preparation of tripeptides of the type Z-Aib-Xaa-Aib-N(Ph)Me (18) by following the protocol of the ‘azirine/ox-azolone method’: treatment of Z- Aib with 1 to give the dipeptide amide 15, followed by selective hydrolysis to the corresponding acid 16 and coupling with the 2,2-dimethyl-2H-azirin-3- amine 17 gave 18, again in high yield (Scheme 5). With some selected examples of 18, the selective deprotection of the amino and the carboxy group, respectively, was demonstrated (Scheme 6). The solid-state conformations of the protected tripeptides 18a-d, as well as that of the corresponding carbocyclic analogue 18e, were determined by X-ray crystallography (Figs. 1- 3 and Tables 1-3). All five tripeprides adopt a beta-turn conformation of type III or III. The solvent dependence of the chemical shifts of the NH resonances (Fig. 6) suggests that there is an intramolecular H-bond between H-N(4) and O(11) in all cases, which is an indication that a relatively rigid beta-turn structure also persists in solution. Surprisingly, the tripeptide acid 20a shows no intramolecular H-bond in the crystalline state (Fig. 7); O(11) is involved in an intermolecular H-bond with the OH group of the carboxy function.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Product Details of 40191-32-0, you can also check out more blogs about40191-32-0
