    摘要: An improved process for making Alpha -(carboxy)arylacetyl derivatives of 6-aminopenicillanic acid esters useful as antibacterial agents and as intermediates for 6-( Alpha (carboxy)arylacetamido)penicillanic acids which comprises acylation of a 6-aminopenicillanic acid ester with a monacid halide of an arylmalonic acid silyl ester in anhydrous reactioninert solvent.

    摘要: 3,4,10,11-Dibenzo-1,8-diazacyclotetradeca-3,1-dienes and pharmaceutically acceptable acid addition salts useful as hypoglycemic agents, obtained by cyclization of the N-formyl derivatives of phenylpropylamine or substituted phenylpropylamines to form dihydrobenzazepin, which is dimerized to the corresponding dibenzodiazacyclotetradecatetraene, which is then reduced to the corresponding diazacyclotetradecadiene.
