corresponding amide derivatives with triphenylphosphine or tributylphosphine in xylene at room temperature gave quinazolinones 2 and 4 in excellent yields via the Staudinger reaction, followed by the intramolecular aza-Wittig reaction.
Various calcilytic compounds and pharmaceutical compositions containing these compounds are disclosed. Calcilytic compounds are compounds capable of inhibiting calcium receptor activity. Techniques which can be used to obtain calcilytic compounds and uses of calcilyitc compounds as calcium receptor antagonists are also disclosed.
