Ipso-Nitrosation of arylboronic acids with chlorotrimethylsilane and sodium nitrite
Nitroso compounds are versatile reagents in synthetic organic chemistry. Herein, we disclose a feasible protocol for the ipso-nitrosation of aryl boronic acids using chlorotrimethylsilane-sodium nitrite unison as nitrosation reagent system.

A highly stereoselective organocatalytic tandem aminoxylation/aza-Michael reaction for the synthesis of tetrahydro-1,2-oxazines
(Chemical Equation Presented) A facile stereoselective synthesis of multifunctionalized tetrahydro-1,2-oxazines (THOs) has been achieved by the organocatalyzed asymmetric tandem α-aminoxylation/aza-Michael reaction for the C-O/C -N bond formations in moderate to good yields with excellent diastereo- (>99:1 dr) and enantioselectivities (92% to >99% ee).
Diastereo- and enantioselective synthesis of nitroso Diels-Alder-type bicycloketones using dienamine: Mechanistic insight into sequential nitroso aldol/Michael reaction and application for optically pure 1-amino-3,4-diol synthesis
This article presents complete diastereo- and highly enantioselective synthesis of nitroso Diels-Alder-type bicycloketones using dienamine. With the hydrogen bonding of two hydroxyls in the bulky binaphthol 1c, high enantioselectivities and complete diast
