    摘要： The present invention discloses novel 6-acylamino-2,2-dimethyl-3-phosphonopenams and certain lower alkyl esters thereof possessing antibacterial activity, methods for their production, and intermediates therefor; the production comprises the steps of reacting 6-triphenylmethylamino-2,2-dimethylpenam-3-carboxylic acid with lead tetraacetate to form the corresponding 3-acetoxy compound, the latter is converted to .alpha.-triphenylmethylamino-5,5-dimethyl-3-thiazoline-2-acetic acid which is condensed with dimethyl phosphite to produce .alpha.-triphenylmethylamino-5,5-dimethyl-4(0,0-dimethylphosphono)-thiazolidine-2-acetic acid which is cyclized to 6-triphenylmethylamino-2,2-dimethyl-3-(0,0-dimethylphosphono)penam and the latter is subsequently deblocked and acylated.

    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.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.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.
