专利号:US-3933830-A 优先权日:1974-09-10 标 题 :Process for the synthesis of 4-(2-pyridylamido ethyl) piperidines 发明人:BARTH WAYNE E; KUHLA DONALD E 权利人:PFIZER 摘要:Disclosed herein is an improved process for the preparation of known hypoglycemic piperidinesulfamylureas of the structure ##EQU1## wherein R is selected from the group consisting of 3-(2-methoxy)pyridyl, 3-(2-ethoxy)pyridyl and 2-(4-chloro)pyridyl and R' is selected from the group consisting of bicyclo[2.2.1]hept-5-en-2-yl-endo-methyl, bicyclo[2.2.1]hept-2-yl-endo-methyl, 7-oxabicyclo[2.2.1]hept-2-yl-methyl, 1-adamantyl and cycloalkyl having from five to eight carbon atoms. n Said process comprises contacting 4-(2-pyridyl-amidoethyl) piperidine of the structure ##EQU2## with substantially one equivalent of sulfamide thereby exclusively sulfonating the piperidine nitrogen atom. Said 4-(2-pyridylamidoethyl)piperidines from the corresponding 4-(2-pyridylamidoethyl) pyridines by selectively activating the more basic nitrogen atom of said pyridine compound either by N-alkylation or by contact with acid and then exclusively reducing the activated pyridine ring with either hydrogen alone or in combination with a metal hydride. Said 4-(2-pyridylamidoethyl)pyridines are produced by contacting 4-(2-aminoethyl)pyridine with a pyridyl acid chloride of the formula R(C=O)Cl. The piperidine sulfonamides produced by the process of the instant invention are converted to the desired hypoglycemic agent by methods well-known to those skilled in the art. n The 4-(2-pyridylamidoethyl)pyridines and piperidines of the instant invention are themselves novel compounds useful as intermediates in the synthesis of piperidine sulfamylurea hypoglycemic agents.

专利号:WO-2015131100-A1 优先权日:2014-02-28 标题:Ligand-controlled c(sp3)-h arylation and olefination in synthesis of unnatural chiral alpha amino acids 发明人:YU JIN-QUAN 权利人:SCRIPPS RESEARCH INST 摘要:The use of ligands to tune the reactivity and selectivity of transition metal-catalysts for C(-sp3)-H bond functionalization is a central challenge in synthetic organic chemistry. Herein, we report a rare example of catalyst-controlled C(sp3)-H arylation using pyridine and quinoline derivatives: the former promotes exclusive monoarylation, whereas the latter activates the catalyst further to achieve diarylation. Successive application of these ligands enables the sequential diarylation of a methyl group in an alanine derivative with two different aryl iodides, affording a wide range of β-Ar-p-Ar ' -cc-amino acids with excellent levels of diastereoselectivity (d.r. > 20:1). Both configurations of the β-chiral center can be accessed by choosing the order in which the aryl groups are installed. The use of a quinoline derivative as a ligand also enables C(sp3)-H olefination of a protected alanine.
