Reactions of derivatives of sulfamic acid with epoxides

Steviol Glycosides: Chemical Diversity, Metabolism, and Function

“…336 Additionally, when photoperiodism changes from short to long days while at the same latitude, the intensity of irradiation becomes an increasingly important determinant affecting leaf biomass accumulation. 328,337 In one experiment, an irradiation of 100 W/m 2 during a 16 h photoperiod doubled the dry leaf biomass per plant when compared to an irradiation of 50 W/m 2 under the same photoperiod. 328 For in vitro production of steviol glycosides, optimal irradiance was shown to be 35 to 45 W/m 2 , which was almost 3-fold lower than that for in vivo plants.…”

“…Under natural conditions, long-day conditions of 16 h or more are found only during the summer period above 50° latitude. Yet in these regions, other abiotic factors such as temperature and irradiance are generally not ideal for the field production of S. rebaudiana . , One way to solve the issue of providing long-day regimes during short-day conditions is by directing photoreceptor responses. As light plays a tremendous role in plant growth, influencing photomorphogenesis by photoreceptor stimulation has become a major topic in plant physiology.…”

Sulfamic Acid and Its N- and O-Substituted Derivatives

“…Thus, 3-chloro-2-hydroxypropylsulfamate, RN-(SO 3 M)CH 2 CH(OH)CH 2 Cl, hydrolyzes in basic conditions to 2,3-dihydroxypropylsulfamate, RN(SO 3 M)CH 2 CH(OH)-CH 2 OH, 126 and reacts with amines to give 1,3-diamino-2propanols, RNHCH 2 CH(OH)CH 2 NHR 1 . 127 They probed the reaction of N-alkylsulfamates with urea and formaldehyde 128 giving 1-(N-alkylnitroaminomethyl)-3-nitroureas, RN(NO 2 )-CH 2 NHCONHNO 2 , and with guanidine, nitroguanidine, H 2 NC(NNO 2 )NH 2 , 3,4-diaminofurazan, and 3-amino-4methylfurazan 129 giving various nitroproducts, for example, nitroguanidine gave H 2 NC(NNO 2 )NHCH 2 N(NO 2 )Me. Reaction of aliphatic amines with N-alkylsulfamates and formaldehyde in HNO 3 and acetic anhydride resulted in formation of 5-alkyl-1,3-dinitro-1,3,5-triazacyclohexanes 26 and linear nitramines 27 in reasonable yields.…”

“…Hydroxypropylsulfamates have been shown to undergo further reactions. Thus, 3-chloro-2-hydroxypropylsulfamate, RN(SO 3 M)CH 2 CH(OH)CH 2 Cl, hydrolyzes in basic conditions to 2,3-dihydroxypropylsulfamate, RN(SO 3 M)CH 2 CH(OH)CH 2 OH, and reacts with amines to give 1,3-diamino-2-propanols, RNHCH 2 CH(OH)CH 2 NHR 1 . They probed the reaction of N -alkylsulfamates with urea and formaldehyde giving 1-( N -alkylnitroaminomethyl)-3-nitroureas, RN(NO 2 )CH 2 NHCONHNO 2 , and with guanidine, nitroguanidine, H 2 NC(NNO 2 )NH 2 , 3,4-diaminofurazan, and 3-amino-4-methylfurazan giving various nitroproducts, for example, nitroguanidine gave H 2 NC(NNO 2 )NHCH 2 N(NO 2 )Me.…”
