Process for preparing derivatives of baccatine III and of 10-deacetylbaccatine III, of general formula (I), in which R is hydrogen or acetyl, by condensation of an acid of general formula (II) with a derivative of baccatine III or of 10-deacetylbaccatine III of general formula (III), R.sub.1, R.sub.2 and R.sub.3 denoting hydroxy-protecting groups, followed by the replacement of the protecting groups by hydrogen. ##STR1##
摘要:
A process for preparing a 4,5-tri or tetramethylene-4-isothiazoline-3-one comprises cyclizing a 2-alkyl or aralkyl thio-1-cycloalkene-1-carboxamide in the form of its sulfoxide in an organic solvent in the presence of a acid chloride and adding to the resulting 4,5-tri or tetramethylene-4-isothiazoline-3-one hydrochloride a mineral or organic base or water so as to free the 4,5-tri or tetramethylene-4-isothiazoline-3-one in the form of a free base.
摘要:
The present invention relates to a system (1) and an associated method for managing audio warning messages in an aircraft.The system (1) comprises a plurality of monitoring systems (10, 20) capable of detecting the establishment of at least one warning condition (CA), and comprises a central broadcasting module (40), to which each of the monitoring systems is connected and which is capable of broadcasting an audio message (SIG) corresponding to a detected warning condition.In particular, in this system (1), the said central broadcasting module (40) comprises means (402, 420) for determining at least one priority warning condition among the warning conditions detected by the monitoring systems, and means (410, 430) for generating at least one audio message (SIG) corresponding to the at least one determined priority warning condition, in order to broadcast it.
