Reaction Conditions:

with 1-hydroxy-3H-benz[d][1,2]iodoxole-1,3-dione in ethyl acetateReflux;

Steps:

1 tert-butyl 3-formylazetidine-1-carboxylate (1.3)
To a stirringsolutionof tert-butyl 3-(hydroxymethyl)azetidine-1-carboxylate(20.96 g, 112 mmol) in EA (500 ml)was added IBX (62.69 g, 224 mmol) and the reaction was refluxed overnight. The reaction was cooledto rt, PE (500 ml)was added and the reaction mixture was filtered. The filtrate was concentrated under reduced pressureto give compound1.3 as yellow oil product (20.56 g,99%). 1H NMR (400 MHz, CDCI3) i5 1.44 (s, 9 H), 3.32-3.4015 (m, 1 H), 4.07-4.14 (m, 4 H), 9.85 (d, J = 2.0Hz, 3 H).
