The present invention provides novel conformationally-defined macrocyclic compounds that can function as selective modulators of the ghrelin receptor (growth hormone secretagogue receptor, GHS-R1a and subtypes, isoforms and variants thereof). Methods of synthesizing the novel compounds are also described herein. These compounds are useful as agonists of the ghrelin receptor and as medicaments for treatment and prevention of a range of medical conditions including, but not limited to, metabolic and/or endocrine disorders, gastrointestinal disorders, cardiovascular disorders, obesity and obesity-associated disorders, central nervous system disorders, bone disorders, genetic disorders, hyperproliferative disorders and inflammatory disorders.

Baeyer−Villigermonooxygenases have been tested in the oxidation of racemic benzofused ketones. When employing a single mutant of phenylacetone monooxygenase (M446G PAMO) under the proper reaction conditions, it was possible to achieve 3-substituted 3,4-dihydroisocoumarins with high yields and optical purities through regioselective dynamic kinetic resolution processes.

has been achieved through the merger of iminium ion catalysis and transition-metal catalysis such that asymmetricinduction derives from a readily accessible, inexpensive chiral nonracemic secondary amine catalyst rather than a chiral nonracemic phosphine as is typical of conventional asymmetric hydroacylation methods.

Transamination from 1-aminotetralins and 1-aminoindanes with differentiation of stereochemistry at both the site of reaction and at a remote stereocentre.
It is shown unequivocally by chemical correlations (cf. Schemes 1--3) and Raman optical activity spectra (cf. Fig. 1 and 2) that the (R)-configuration has to be attributed to (+)-1-methylindane ((+)-1). This is in contradiction to an earlier assignment of the (R)-configuration to (−)-1[2] which was based on the (R)-configuration of (+)-indane-1-carboxylic acid (3) [11].
