| titleOfInvention | Sulphone substd polyisoprenoids - inters for carotenoids etc |
| abstract | Cpds. (I): (one of X and Y = -SO2R, other is H; R = alkyl, alkenyl aralkyl, alkaryl, all opt. substd. by electron attracting or releasing gps; A = (5n+1)C hydrocarbyl; n = 0-5, opt. satd or contng. >=1 opt. conjugated acetylenic >=1 or ethylenic bonds, when n = 1-5, A may be substd. by alkyl or functional gps. and when n >=2 it may form a ring opt. with alkyl or functional substits, esp. opt. protected oxo or OH; or A is as for Q; Q = CH3, opt. halo substd; SR' or SO2R' (R' is as R), CH2OH, opt. esterified on etherified, CHO, opt protected, CO2H or chloride, esters, nitrile therefrom, or Q is a hydrocarbyl gp. as defined for A provided that A and Q are not simultaneously 6-(2,6,6-trimethylcyclohexen-1-y)-4-methyl-hexa-1,3,5-trienyl). (I), are prepd. by reacting Q (or A) substd. isobutenylsulphone with A (or Q) substd. isobutenyl halide in presence of base, are inters, for tail-to-tail polymerised polyisoprenoids esp. carotenoids. |
