An efficient and highly enantioselective phase-transfer-catalyzedaza-Michaelreaction of 3,3-dinitroazetidine, as N-centered nucleophile, to α,β-unsaturated ketones has been achieved using a quinidine-based phase-transfer catalyst (0.5–1 mol %), providing chiral N-substituted 3,3-dinitroazetidines in good yields (up to 99%) and excellent enantioselectivities (90–95% ee). This is the first example

The compound, 3,3-dinitroazetidine, and a process of preparing 3,3-dinitroazetidine including reacting a mixture of 1-tertiary-butyl-3,3-dinitroazetidine and benzyl chloroformate to form 1-(benzyloxycarbonyl)-3,3-dinitroazetidine, reacting the 1-(benzyloxycarbonyl)-3,3-dinitroazetidine and trifluoromethanesulfonic acid to form 3,3-dinitroazetidinium trifluoromethanesulfonate, and neutralizing the 3,3-dinitroazetidinium trifluoromethanesulfonate with a base to form 3,3-dinitroazetidine are provided. Salts of the 3,3-dinitroazetidine and preparation of such salts are also disclosed.
A process of preparing 1,3,3-trinitroazetidine including forming a 5-hydroxymethyl-5-nitro-1-alkyltetrahydro-1,3-oxazine, e.g., reacting a 1,3,5-trialkyl hexahydrotriazine and tris(hydroxymethyl)nitromethane, ring opening said 5-hydroxymethyl-5-nitro-1-alkyltetrahydro-1,3-oxazine to form a 3-alkylamino-2-hydroxymethyl-2-nitro-1-propanol salt, ring closing said 3-alkylamino-2-hydroxymethyl-2-nitro-1-propanol salt to form a 3-hydroxymethyl-3-nitro-1-alkylazetidine salt, nitrating said 3-hydroxymethyl-3-nitro-1-alkylazetidine salt to form a 1-alkyl-3,3-dinitroazetidine, and converting said 1-alkyl-3,3-dinitroazetidine into 1,3,3-trinitroazetidine is disclosed.
