A glycine Schiff base Michael addition is used in sequence with free radical-mediated aryl amination to ultimately arrive at the ambiguine G ABC-tricycle convergently. Additionally, thermal Diels-Alder cycloaddition of beta-chloromethacrolein with Cohen's diene is used to diastereoselectively construct the D-cyclohexane ring bearing a neopentyl chloride.
