In a paper recently published, the authors carried out the
following synthesis. Draw the major products (Product A &
Product B) that would form. Note: The first step (SOCl2, heat) is
done under dilute conditions to prevent reaction between the
product and other species in solution.

Problem 3 In an early benzodiazepine synthesis, the following reaction was carried out, with the aim of making the first product. Was it reasonable to expect the displacement of chloride when the starting material was treated with methylamine? Show a mechanism to explain what actually happens, and give a rationale for why the ring expansion occurs instead of the first reaction. N CH,CI NCH NHCH CH3NH2 ENO not produced Ph Ph NHCH3 N LNCHCI CH3NH2 actual product Y NO

CONCEPT QUESTIONS Mechanism. While the reaction carried out in lab used potasslum hydroxide as the catalyst, many other catalysts have been developed to increase regioselectivity and stereoselectivity in aldol condensations. One small molecule catalyst commonly used is proline, a naturally occurring amino acid. The mechanism invoives the initial formation of an enamine; predict the structure of this enamine intermediate (Intermediate A), and draw the mechanism for the conversion of intermediate A to Intermediate B. Helpful Hint: The formation of the...
