Ketene Dithioacetals as 1,3-Dipolarophiles. Applications to the Synthesis of Cyclic Amino Acids
Moss, William O.,Bradbury, Robert H.,Hales, Neil J.,Gallagher, Timothy
, p. 51 - 53 (1990)
Intramolecular azide cycloaddition reactions of ketene dithioacetals provide a new route to cyclic amino acids and a stereoselective synthesis of (2S,3S,4R)-3,4-dihydroxyproline (14) based on this methodology is described.

The present invention provides a compound which is useful as a PGI2 receptor agonist, and a pharmaceutical composition. The present invention is directed to a pharmaceutical composition comprising a compound represented by the following formula [1]: (R1 and R2 are the same or different and each represents optionally substituted aryl, Y represents N or CH, Z represents N or CH, A represents NH, NR5, O, S, or ethylene, R5 represents alkyl, D represents alkylene or alkenylene, E represents phenylene or single bond, G represents O, S, or CH2, R3 and R4 are the same or different and each represents hydrogen or alkyl, Q represents carboxy, alkoxycarbonyl, tetrazolyl, carbamoyl, or N-(alkylsulfonyl)carbamoyl), or a pharmaceutically acceptable salt thereof as an active ingredient.

Intramolecular azide cycloaddition reactions of ketene-S,S-acetals proceed to give a reactive imine as the initially-formed intermediate and this mechanism is supported by thermolysis of (18) which gave the stable imine (22).N-Acylation of this intermedia
