A stabilized dehydrosecodine analogue bearing carbomethoxy groups in the 3-and 5- positions of the di-hydropyridine moiety has been prepared and its chemistry studied. Two novel procedures have been developed for this synthesis:(1) the Lewis acid assisted cleavage of an activated indole ether with trimethylsilyl cyanide to form a cyano alcohol and (2) the oxidation of 2-(a-substituted ethy1) indoles with tert-butyl hypochlorite to form the ...
