Compounds of formula (I): wherein A, R1, R2, X, m, and n are as defined in the specification, are selective M3 receptor antagonists and may be used in the treatment of, inter alia, a respiratory disease such as asthma and COPD.
1,3-Dipolar cycloadditions of new mesoionic compounds. Synthesis of 1H-pyrrolo[1,2-c]thiazoles, pyrrolizines and 5,6,7,8-tetrahydroindolizines

We studied the 1,3-dipolar cycloaddition reactions between alkyne dipolarophiles and the new mesoionic compounds 2H,5H,7H-thiazolo[4,3-b]oxazol-2-one (12), 2H,5H,7H-pyrrolo[2,1-b]oxazol-2-one (13) and 2H,5H,7H-oxazolo[3,2-a]pyridin-2-one (14). These 1,3-dipoles were prepared in situ by means of cyclodehydration with acetic anhydride of the corresponding α-substituted 4-oxo-3-thiazolidine- (9), 2-oxo-1-pyrrolidine- (10) and 2-oxo-1-piperidineacetic acids (11). The cycloaddition reactions with alkyne dipolarophiles afforded single 1H-pyrrolo[1,2-c]thiazole, pyrrolizine and 5,6,7,8-tetrahydroindolizine derivatives, or a mixture of the two possible regioisomers, depending on whether symmetrical or unsymmetrical alkynes.

A glyoxylic acid-2-pyrrolidinone adduct leads to N-acyliminium-ion induced intermolecular electrophilic aromatic substitution yielding nitrogen-substituted phenylglycine derivatives, whereas the benzylamide of glyoxylic acid-2-pirrolidinone adduct undergo
