Cycloaddition with Unsaturated Carbohydrates, I. — The 1,3‐Dipolar Cycloaddition of Diphenylnitrile Imine to α‐D‐erythro‐Hex‐2‐enopyranoside
By 1,3‐dipolar cycloaddition of diphenylnitrile imine to ethyl 4,6‐di‐O‐acetyl‐2,3‐dideoxy‐α‐D‐erythro‐hex‐2‐enopyranoside (1) ethyl 4,6‐di‐O‐acetyl‐2,3‐dideoxy‐3′,4′‐dihydro‐2′,5′‐diphenyl‐2′H‐α‐D‐menno‐hexopyranosido[3,2‐c]pyrazole (2a) and the [2,3‐c]‐regioisomer (3a; 2a: 3a = 4:1) were prepared.
