The present invention provides, in part, compounds of Formula I: and pharmaceutically acceptable salts thereof and N-oxides thereof; processes and intermediates for preparation of; and compositions and uses thereof. The present invention further provides D1 agonists with reduced D1R desensitization, D1 agonists with a reduced β- arrestin recruitment activity relative to Dopamine, D1 agonists interacting significantly with the Ser188 but not significantly with the Ser202 of a D1R when binding to the D1R, D1 agonists interacting less strongly with the Asp103 and interacting less strongly with the Ser198 of a D1R when binding to the D1R, and their uses.

Broonsted acid-promoted hydrocyanation of arylalkenes

supporting information; experimental part, p. 5286 - 5289 (2009/12/29)
Nonactivated arylalkenes are effectively converted to tertiary benzylic nitriles in the presence of triflic acid and trimethylsilyl cyanide. The hydrocyanation reactions result in good to excellent yield when electron-donating groups are substituted on the benzene ring. The reaction conditions are mild and relatively safe, notably without need for handling hazardous hydrogen cyanide gas, providing simple and easy access to tertiary benzylic nitriles. The reaction was applied to the preparation of a PDE4 inhibitor (3) as well as a series of analogues.

Combretastatins A-1 and B-1 have been synthesized by coupling MOM-protected p-iodomethoxycatechol with 3,4,5-trimethoxyphenylacetylene in a Sonogashira reaction.
Combretastatin analogs with tubulin binding activity
-
Figure 12, (2008/06/13)
Analogs of combretastatin have been discovered which demonstrate impressive cytotoxicity as well as a remarkable ability to inhibit tubulin polymerization. Such compounds are excellent clinical candidates for the treatment of cancer in humans. In addition, certain of these ligands, as pro-drugs, may well prove to be tumor selective vascular targeting chemotherapeutic agents or to have vascular targeting activity resulting in the selective prevention and/or destruction of nonmalignant proliferating vasculature.
Hydroxyphenstatin and the prodrugs thereof
-
, (2008/06/13)
The benzophenone derivative of combretastatin A-1, designated “hydroxyphenstatin”, was synthesized by compiling a protected bromobenzene and a benzaldehyde to form a benzhydrol which was subsequently oxidized to the ketone. Hydroxyphenstatin was converted

Convergent syntheses of combretastatins A-1 and B-1 were accomplished via coupling of biocatalytically generated p-bromomethoxycatechol with trimethoxyphenylacetylene.
Medium-scale preparation of useful metabolites of aromatic compounds via whole-cell fermentation with recombinant organisms
Endoma, Mary Ann,Bui, Vu P.,Hansen, Jeff,Hudlicky, Tomas
, p. 525 - 532 (2013/09/06)
The whole-cell fermentation of aromatic coumpounds with Escherichia coli JM109 (pDTG601) on a medium scale (10-15L) produces enantiopure cyclohexadienediols. A detailed procedure for the fermentation is described, and yields for several metabolites are provided. A similar procedure using E. coli JM109 (pDTG602) affords catechols. The dienediols are useful for asymmetric synthesis, and several important targets originating from these metabolites are tabulated.

A structure - activity relationship (SAR) study of the South African willow tree (Combretum caffrum) antineoplastic constituent combretastatin A-4 (3b) led to the discovery of a potent cancer cell growth inhibitor designated phenstatin (5a). This benzophenone derivative of combretastatin A-4 showed remarkable antineoplastic activity, and the benzophenone derivative of combretastatin A-1 was therefore synthesized. The benzophenone, designated hydroxyphenstatin (6a), was synthesized by coupling of a protected bromobenzene and a benzaldehyde to give the benzhydrol with subsequent oxidation to the ketone. Hydroxyphenstatin was converted to the sodium phosphate prodrug (6e) by a dibenzyl phosphite phosphorylation and subsequent benzyl cleavage (6a → 6d → 6e). While hydroxyphenstatin (6a) was a potent inhibitor of tubulin polymerization with activity comparable to that of combretastatin A-1 (3a), the phosphorylated derivative (6e) was inactive.
