[reaction: see text] 9-Tosyl-3,4-dihydro-beta-carboline (1) reacted with a ketone in the presence of (S)-proline as a catalyst to give the corresponding addition product in good yield and high enantioselectivity. In the process, a small amount of water was found to affect the stereoselectivity of the products. The system was applied to reaction of compound 1 and 3-buten-2-one to give 3,4,6,7,12,12
The present invention provides for novel compounds of Formula (I) and pharmaceutically acceptable salts and co-crystals thereof which have glucagon receptor antagonist or inverse agonist activity. The present invention further provides for pharmaceutical compositions comprising the same as well as methods of treating, preventing, delaying the time to onset or reducing the risk for the development or progression of a disease or condition for which one or more glucagon receptor antagonist is indicated, including Type I and II diabetes, insulin resistance and hyperglycemia. The present invention also provides for processes of making the compounds of Formula I, including salts and co-crystals thereof, and pharmaceutical compositions comprising the same.

A positive chemically amplified resist composition is disclosed, comprising (a) a compound which generates an acid upon irradiation with active light or radiant ray; (b) a resin insoluble in water but soluble in an aqueous alkali solution; and (c) a low molecular acid-decomposable dissolution inhibitor having a molecular weight of 3,000 or less and containing an acid-decomposable alkyl ester group represented by formula (I), and which increases its solubility in an alkali developer by the action of an acid, and having a sodium content and a potassium content each of 30 ppb or less. Also disclosed is a positive chemically amplified resist composition comprising the foregoing compound (a) and (d) a resin having an acid-decomposable alkyl ester group represented by formula (I), and which increases its solubility in an alkali developer by the action of an acid, and having a sodium content and a potassium content each of 30 ppb or less. Still further disclosed are methods for producing the compounds (c) and (d).
