Abstract The hetero-Diels–Alder reaction between a nitroso dienophile and a conjugated
diene to give the 3, 6-dihydro-2H-1, 2-oxazine scaffold is useful for the synthesis of many …

The nitroso Diels–Alder (NDA) reaction is an attractive strategy for the synthesis of 3, 6-
dihydro-1, 2-oxazines and 1-amino-4-hydroxy-2-ene derivatives. Herein we report the Cu (I) …

The biological importance and wide occurrence of spirane systems in nature have
stimulated studies in spirane chemistry. The fundamental spirane framework consists of two …

Abstract A 4‐substituted‐1‐tosyl‐1, 2, 3‐triazole‐based stereoselective synthesis of
structurally diverse oxaspirocycles is reported. The synthesis involves Rh‐catalyzed loss of …

The regioselectivity of the nitroso‐Diels–Alder reaction between unsymmetrical acyclic
dienes and Boc‐nitroso (Boc= tert‐butoxycarbonyl) reagent or the Wightman chiral …

Abstract The nitroso Diels—Alder (NDA) reaction has occupied an important place in
organic synthesis, and numbers of important compounds and bioactive skeletons have been …

Since 1984, the chemistry of 1, 2-oxazines and their benzo derivatives has been periodically
reviewed in Comprehensive Heterocyclic Chemistry. 1–3 Since the last survey of this topic …

Les cycloadditions de Diels-Alder sont encore aujourd'hui souvent utilisées par les
chimistes organiciens pour la synthèse de systèmes cycliques très substitués. Les …

A modular enantioselective synthesis of spiroketals, spiroethers, and oxabicycles, each
containing a dihydropyran subunit, is described. It is based on the 2, 2‐spiro‐and 2, 6 …

To gain a deeper understanding of the formation of the synthetically important 3, 6‐dihydro‐
2H‐1, 2‐oxazines, the 6‐endo‐trig cyclization of allenyl‐substituted hydroxylamines was …
