N-Nitrosotomatidine

(1R,2S,4S,5S,6S,7S,8R,9S,12S,13S,16S,18S)-5,7,9,13-tetramethyl-1-nitroso-5-oxaspiro[pentacyclo[10.8.0.0^{2,9}.0^{4,8}.0^{13,18}]icosane-6,2-piperidine]-16-ol

C27H44N2O3 (444.3352)


N-Nitrosotomatidine belongs to the class of organic compounds known as spirosolanes and derivatives. These are steroidal alkaloids with a structure containing a spirosolane skeleton. Siporosolane is a polycyclic compound that is characterized by a 1-oxa-6-azaspiro[4.5]decane moiety where the oxolane ring is fused to a docosahydronaphth[2,1:4,5]indene ring system. Spirosolane arises from the conversion of a cholestane side-chain into a bicyclic system containing a piperidine and a tetrahydrofuran ring. N-Nitrosotomatidine is a moderately basic compound (based on its pKa). N-Nitrosotomatidine has been identified in tomatoes. Present in tomatoes. N-Nitrosotomatidine is found in garden tomato.
