  Amide bond replacements : incorporation of a 2,5,5-trisubstituted imidazoline into dipeptides and into a CCK-4 derivative.

  摘要：

  Synthetic methodology for the introduction of a 2,5,5-trisubstituted imidazoline ring as an amide replacement into dipeptide derivatives of Phe, Trp, Lys (N-epsilon-CBZ) and Nle is described. This replacement is also incorporated into the Trp-Nle bond of the tetrapeptide CCK-4 derivative Trp-Nle-Asp-Phe-NH2 and the pentagastrin derivative Gly-Trp-Nle-Asp-Phe-NH2.

  Triple Role of Phenylselenonyl Group Enabled a One-Pot Synthesis of 1,3-Oxazinan-2-ones From α-Isocyanoacetates, Phenyl Vinyl Selenones, and Water

  摘要：

  Reaction of alpha-substituted alpha-isocyanoacetates with phenyl vinyl selenones in the presence of a catalytic amount of base (DBU or Et3N, 0.05-0.1 equiv) followed by addition of p-toluenesulfonic acid (PTSA, 0.1-0.2 equiv) afforded 4,4,5-trisubstituted 1,3-oxazinan-2-ones in good to excellent yields. Enantiomerically enriched heterocycles can also be prepared using a Cinchona alkaloid-derived bifunctional organocatalyst for the Michael addition step. The phenylselenonyl group served as an activator for the Michael addition, a leaving group and a latent oxidant in this integrated reaction sequence.

• PREPARATION OF DIAZO AND DIAZONIUM COMPOUNDS
  申请人：Raines Ronald Thaddeus

  公开号：US20100125132A1

  公开（公告）日：2010-05-20

  A method for making diazo-compounds, diazonium salts thereof and other protected forms of these compounds. Diaz-compounds are prepared by reaction of a tertiary phosphine reagent carrying a reactive carbonyl group with an azide. The reaction can also generate an acyl triazene which can be converted thermally or by addition of base to form the diazo-compound or the acyl triazene can be isolated. The method is particularly useful for conversion of azides carrying one or more electron withdrawing groups to diazo-compounds. The method can be carried out in aqueous medium under mild conditions and is particularly useful for conversion of azido sugars to diazo-compound and diazonium salts thereof under physiological conditions. Tertiary phosphine reagents, particularly those that are water-soluble, and precursors for preparation of the reagents are provided.

• Solid-Phase Synthesis of Amino Acid Derived <i>N</i>-Unsubstituted Pyrazoles via Sydnones

  日期：2009.5.21

  The solid support acts as a protecting group for the amino acid. N-Protected amino acid is N-nitrosated, and the subsequent treatment with acetic anhydride in a microwave reactor yields mesoionic sydnones that react in situ in 1,3-dipolar cycloaddition reactions with alkynes. Traceless cleavage of the products gives N-unsubstituted pyrazoles in high overall yields.

  This work describes the use of a 2,5,5-trisubstituted imidazoline as an amide bond replacement. The replacement is incorporated into dipeptide derivatives of Phe, Trp, Lys and Nle and also into the CCK-4 analogue Trp-Nle-Asp-Phe-NH2 and the pentagastrin analogue Gly-Trp-Nle-Asp-Phe-NH2. The amide bond replacement is synthesised in enantiomerically and diastereomerically pure form.

  Visible-light-induced deaminative alkylation of Katritzky salts with silyl enol ethers has been developed. The reaction can proceed efficiently through electron donor–acceptor complex formation, avoiding the use of precious metal complexes or synthetically elaborate organic dyes. A series of functionalized γ-ketoesters was successfully obtained with good functional group tolerance and compatibility under mild

  A Suzuki–Miyaura cross-coupling of α-pyridinium esters and arylboroxines has been developed. Combined with formation of the pyridinium salts from amino acid derivatives, this method enables amino acid derivatives to be efficiently transformed into α-aryl esters and amides. Under the mild conditions, broad functional group tolerance on both the amino acid derivatives and the arylboroxine are observed
