introduced novel derivatives with 40-fold T-type selectivity over L-type calcium channels. Along these lines, substitution of the DHP core with various analogues favored T-selectivity and may serve as novel pharmacophores. Several dihydropyrimidine (DHPM) mimics were introduced by Squibb as potential candidates. As a continuation of this approach, the current study describes the synthesis of Novel N3 substituted

Sulfonyloxyacetylchloride 1 reagieren mit Thioimidsäureestern 2 in Gegenwart von Triäthylamin zu trans-3-Sulfonyloxy-4-alkylthio-2-azetidinonen 3. Ein weiterer Weg zu dieser neuen Klasse von β-Lactamderivaten besteht in der Reaktion von Acyloxyacetylchloriden 8 mit Thioimidsäureestern 2, Verseifung der gebildeten 3-Acyloxy-2-azetidinone 9 zu den 3-Hydroxyverbindungen 10 und deren Veresterung mit Sulfonsäurechloriden
