Catalytic and metal-free intramolecular hydroalkoxylation of alkynes

Benzyltrimethylammonium hydroxide act as an efficient metal-free catalyst for the intramolecular hydroalkoxylation of alkynes. Notably, the use of microwave irradiation allowed reaction to operate in only two minutes. Under optimized reaction conditions, linear alkynes bearing aryl and heteroaryl substituents were successfully cyclized with good level of stereoselectivity.

ALKYLATION REACTIONS OF ANIONS DERIVED FROM 2-BENZENESULPHONYL TETRAHYDROPYRAN AND THEIR APPLICATION TO SPIROKETAL SYNTHESIS

Reaction of 3,4-dihydro-2H-pyran or 2-methoxytetrahydropyran with benzenesulphinic acid gave 2-benzenesulphonyl tetrahydropyran (1).Deprotonation of (1) followed by alkylation with carbonyl compounds or halides gave cyclic enol ether addition products by
