摘要:
The present invention provides analogs of benzoquinone-containing ansamycins and uses thereof for treating and modulating disorders associated with hyperproliferation, such as cancer. The present invention provides analogs of benzoquinone-containing ansamycins where the benzoquinone is reduced to a hydroquinone and trapped by reaction with a suitable acid, preferably ones that increase the solubility and air stability of the resulting 17-ammonium hydroquinone ansamycin analog.

摘要:
Synthetic methods for solution and solid-phase synthesis of combinatorial libraries of dihydro-quinazolinones, including synthesis of 2,3-dihydro-3-alkoxy-4(1H)-quinazolinones or 2,3-dihydro-3-hydroxy-4(1H)-quinazolinones via the Lewis-acid catalyzed reaction of an appropriate 2-aminobenzamide with an aldehyde at ambient temperature performed on a solid support or in solution.
摘要:
A two-step process for the conversion of a trans-1-amino-2-hydroxycycloalkane stereoselectively to a cis-1-amino-2-hydroxycycloalkane is disclosed. The novel step, a one-step hydrolysis with formal inversion, can be used to convert an amide of a trans-1-amino-2-hydroxycycloalkane to a cis-1-amino-2-hydroxycycloalkane. Methods for obtaining the trans-1-amino-2-hydroxycycloalkanes and their amides from alkenes are also disclosed. Novel, optically active 1-amido-2-indanols and 1-amino-2-alkanols are also disclosed.
