A tandem deprotection-cyclization reaction of 1,1-diacylcyclopropanes is described which allows rapid access to structurally diverse 2,3-disubstituted chromones in good yields, and with straightforward purification. The utility of this reaction is showcas

A facile and diversified synthesis of functionalized CF2-containing benzoxepine derivatives via photoredox catalysis was achieved in this work. This novel protocol features broad substrate scope, mild reaction conditions, operational simplicity, easy scale-up, and versatile derivatization, which would facilitate its practical and broad applications in the construction of valuable and synthetically challenging heterocycles.

The effect of variation of the rigid part of the parent Cram hemispherand 1a on the preorganization of the macrocyclic cavity has been studied.Four novel 18-membered hemispherands (3,4a-c)have been synthesized via a novel multistep route using 2,6-di- and
