General description

(Isopropenyloxy)trimethylsilane is an enol silyl ether. It participates as nucleophile in Lewis acid-promoted C3-nucleophile substitution of tetracyclic bromide. It is reported to participate in the total synthesis of (±)-powelline. It is reported to participate in dityltin bis(triflate) catalyzed Michael addition reaction of enol silyl ethers.

Concise and enantioselective total syntheses of (+)-naseseazines A and B are described. Our regioselective and directed dimerization of diketopiperazines provides their critical C3-C(sp(2)) linkages, an assembly with plausible biogenetic relevance. We revise the absolute stereochemistry of (+)-naseseazines A and B.
