The present invention relates to a process of synthesis of 3,3 dipheylpropylamines, which may be used as pharmaceutical intermediates in the preparation of their pharmacologically active derivatives such as fesoterodine, tolterodine, their enantiomers, pharmaceutically acceptable salts and related compounds useful as antimuscarinic agents.

unprotected tartaricacid 1 by acyl chlorides to the corresponding monoacyltartaric acids 2 has been shown. Several unusual cases in the acylation of 1 are observed; it has been found that two routes of acylation are possible. In the benzoylation of 1, in addition to the expected products, the formation of a previously undescribed monobenzoyltartaric anhydride 7a is reported. An unusual DME cleavage
The synthesis and metal complexation of chiraldepsipeptidedendrimers 3 and 7 containing an ethylenediaminetetraacetic acid (EDTA) ester-derived core is reported. The EDTA ester cavity of these dendrimers selectively complexes Zn(2+) and Cu(2+) ions leading to diastereoselective folding. To elucidate the coordination motif in the resulting "foldamers" of 3-ZnCl(2), 7-ZnCl(2), 3-CuCl(2), and 7-CuCl(2)
Use of 1,3-Dioxin-4-ones and Related Compounds in Synthesis. XLIV. Asymmetric Aldol Reaction of 4-Trimethylsiloxy-6-methylene-1,3-dioxines: Use of Tartaric Acid-Derived (Acyloxy)borane Complex as the Catalyst.
A novel enantioselective synthesis of 1, 3-dioxin-4-ones having a 2-hydroxylated alkyl group at the 6-position has been accomplished by chiral tartaric acid-derived acylborane-mediated aldol condensation of the silyl enol ether derived from 6-methyl-derivatives of 1, 3-dioxin-4-one with achiral aldehydes.
