YieldReaction ConditionsOperation in experiment
82.6% 1. Synthesis of tert-butyl 6-(2-ethoxy-2-oxoethylidene)-2-azaspiro[3.3]heptane-2-carboxylate) A mixture of t-BuOK (3.98 g, 35.47 mmol, 2.498 equiv) and ethyl 2-(bromotriphenyl-$1?[5]-phosphanyl)acetate (15.2 g, 35.41 mmol, 2.493 equiv) in THF (90 mL) in a 250-mL round-bottom flask was stirred for 1 hour at room temperature. Then <strong>[1181816-12-5]tert-butyl 6-oxo-2-azaspiro[3.3]heptane-2-carboxylate</strong> (3 g, 14.20 mmol, 1 equiv) was added and the reaction mixture was stirred for an additional 6 hours at 35° C. Then filtered through Celite and filter cake was washed with THF. The crude was subjected to a silica gel column with ethyl acetate/petroleum ether (1:5). This resulted in 3.3 g (82.60percent) of tert-butyl 6-(2-ethoxy-2-oxoethylidene)-2-azaspiro[3.3]heptane-2-carboxylate as a colorless oil. LC-MS (ES+): m/z 226.1 [M-(t-Bu)+H+], tR=1.267 min, (2.0 minute run).
