An intermolecular [2+2] cycloaddition reaction for the synthesis of 1,2-dimethylenecyclobutane derivatives from the commercially available starting materials aryl acetylenes, nBuLi, formamides, and trimethylsilyl cyanide (TMSCN) has been achieved. This reaction displays high regio- and stereoselectivities due to the captodative effect. The mechanism of the reaction has been investigated by the deuterium labeling experiments and DFT calculations. Cycloaddition of captodative allenes: A regio- and stereoselective intermolecular [2+2] cycloaddition of captodative allenes (in situ generated) for the efficient synthesis of substituted 1,2-dimethylenecyclobutanes is disclosed (see scheme; TMS = trimethylsilyl). The mechanism of the reaction has been investigated by deuterium labeling experiments and the selectivity has been studied by DFT calculations.

Novel quinazoline embellished analogues of 1,5-benzodiazepine (6, 9, 13, 17, 21 and 24) were synthesized using one-pot domino approach. Structure of the compounds synthesized, were established with the help of IR, 1H NMR, 13C NMR and
βUnsaturated acyl cyanides as new bis-electrophiles for enantioselective organocatalyzed formal [3+3]spiroannulation

α,β-Unsaturated acyl cyanides are key bis-electrophile substrates for successful domino enantioselective organocatalyzed Michael-intramolecular acylation domino sequences. This new reactivity has been applied to the synthesis of enantioenriched azaspiro[4
