일반 설명
2H-1,4-Benzoxazin-3(4H)-one, a benzoxazine derivative, is a heterocyclic building block for various natural and synthetic organic compounds.[1] It has been reported as an intermediate during the biogenesis of cyclic hydoxamic acids in maize.[2] Its standard molar enthalpy of formation and tautomerization energy of its tautomers has been evaluated by calorimetric and computational methods.[3] It has been synthesized by reacting o-aminophenol with chloroacetyl chloride in the presence of butanone and aqueous NaHCO3.[4]

A new inhibitor of in vitro tumor cell replication, cappamensin A (1) (2H-1,4-benzoxazin-3(4H)-one, 6-methoxy-2-methyl-4-carbaldehyde), was isolated from the roots of Capparis sikkimensis subsp. formosana using bioactivity-guided fractionation. The structure of 1 was established by spectroscopic methods, including 2D NMR analyses.

We report here the Sn-catalyzed mild protocol for ring expansion of peroxyoxindoles to afford the series of substituted-2H-benzo[b][1,4]oxazin-3(4H)-one derivatives. In this protocol, we showed the in situ conversion of tert-butyl peroxy compounds into peresters with the aid of external esters
