Efficient preparations of acylamides, acylcarbamates and acylureas from alk-1-en-2-yl esters
摘要:
Acylamides, acylcarbamates and acylureas have been synthesized by acylation of amides, carbamates and ureas sodium salts with alk-1-en-2-yl esters prepared with [Ru(mu-O2CH)(CO)(2)(PPh(3))](2) as catalyst.

The alkenyl derivatives [(C6Me6)PMe3)ClRu-C(OMe)CHR] IIIa (RMe) and IIIb (RPh) have been prepared by deprotonation of the corresponding carbene complexes [(C6Me6)(PMe3)ClRuC(OMe)CH2R][PF6−] II with Me3COK. Complexes III can be used as efficient catalysts for the addition of functional carboxylic acids to terminal alkynes to give dioxolanone 4, from R(−)mandelic acid, or methacrylates of the type
