Leírás

Alkalmazás

N,N-Dimethylmethyleneiminium chloride (Böhme′s salt) is a dimethylaminomethylating agent that can be used as one of the key reagents in the following applications:

• Electrophilic aminomethylation of aldehydes and ketones to synthesize corresponding Mannich products, also known as Mannich reaction.
• Preparation of dihydronaphthyridinones as HIV-1 integrase inhibitors.
• Preparation of cyanotetrahydrooxo-β-carbolines via cyclocondensation of cyanomethyl indole-2-carboxylate with ammonia.
• Asymmetric synthesis of phalarine via stereospecific Pictet-Spengler cyclocondensation and traceless chirality transfer from L-tryptophan.
• Synthesis of functionalized diarylpyrrolizines as inhibitors of microsomal prostaglandin E2 synthase-1 (mPGES-1) and 5-lipoxygenase (5-LOX).
• Synthesis of (±)-phalarine with the rearrangement of an azaspiroindolenine and Gassman oxindole preparation as key steps.
