An aza-ene reaction has been used for the first time for the synthesis of two 5-membered lactam-hydrazides, each with a built-in allylsilane terminator for further elaboration. One of the lactam-hydrazides was transformed via an allylsilane-hydrazoni

The [2.2.1]-bicyclic ketone 6 , a potential synthetic precursor to CP-225,917, was prepared by a sequence beginning with Diels–Alder reaction between dimethyl fumarate and the silylated cyclopentadiene 38 . The adduct 40 was subjected to Tamao–Fl

The reaction of diethyl azodicarboxylate with homoallylic silanes capable of two modes of reaction give ene adducts by preferential abstraction of allylic hydrogens nearer the silyl group. This regioselectivity has been exploited in the synthesis of
