Reagents available g. WebJul 3, 2024 · Dimethyl malonate is a good nucleophile on account of the two ester groups on either side of the central carbon atom. It has a p K a of 12.9, which is extremely acidic for a C − H bond. The first step is a Michael addition. The resultant enolate will equilibrate, enabling it to form a much more stable 6 membered ring. customer journey template google slides
