Three syntheses of the protein kinase C activator, (-)-indolactam V, are described and are compared for their potential utility in the preparation of ILV analogs. In one route the 4-amino functionality is introduced regiospecifically during the construction of the indole portion and enantiomeric control is achieved by the alkylation of the amine with a triflate derived from d-valine. One of the routes

compounds can be prepared. These methods supplement our previous work that established routes for the synthesis of 7- and 8-substituted 7-deazaguanines. Emphasis is placed on the properties of 2-thioalkyl pyrimidines as intermediates because they provide the basis for a traceless solid-state synthesis of purines, pteridines, and their analogues. Compounds prepared have been assessed in a primary screen for

nitriles 14–16, proceeded under thermal as well as underhighpressure conditions with complete regioselectivity to give Δ4-1,2,4-oxadiazolines 17–19. In general, the cycloaddition seemed to be controlled by a HOMO(nitrone)- LUMO(nitrile) interaction. However, a crossover in the orbital control is probable observed with nitrile 16c. Nitrone-nitrile cycloadditions are normal typeII cycloadditions so that
