Abstract: Cyclic ethers have been effectively synthesized via the intramolecular cyclization of diols using trimethyl phosphate and NaH. The present cyclization could proceed at room temperature to produce 5-7 membered cyclic ethers in good to excellent… read more here.

Abstract: Frustrated Lewis pairs (FLPs) are now ubiquitous as metal-free catalysts in an array of different chemical transformations. In this paper we show that this reactivity can be transferred to a polymeric system, offering advantageous opportunities… read more here.

Abstract: Abstract An unprecedented non-isoprenoid oxocine carboxylate cyclic ether characterised as (3S, 4R, 5S, 6Z)-3-((R)-hexan-2′-yl)-3,4,5,8-tetrahydro-4-methyl-2H-oxocin-5-yl acetate was isolated from the ethyl acetate–methanol extract of the red seaweed Kappaphycus alvarezii. The structure, as well as its relative… read more here.
