Provided herein is a process for the transfer-hydrogenation of ketone analogs of members of the jervine type of Veratrum alkaloids, such as cyclopamine. Also provided herein are novel ruthenium transfer-hydrogenation catalysts.
Provided herein is a process for the transfer-hydrogenation of ketone analogs of members of the jervine type of
Veratrum
alkaloids, such as cyclopamine. Also provided herein are novel ruthenium transfer-hydrogenation catalysts.
The invention provides novel derivatives of cyclopamine having the following formula:
wherein the nature of the moieties R1, R2, R3, R4, R7, R7', R8 and R9 is defined in appended claim 1.
